d170c4b57a Add -f[no-]declspec to control recognition of __declspec as a keyword
In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes.  It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure).  There is a
desire to support __declspec in Playstation code, and possibly other
environments.  This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword.  Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

Diagnose when a pointer to const T is used as the first argument in at atomic
builtin unless that builtin is a load operation. This is already checked for
C11 atomics builtins but not for __atomic ones.

Per Intel intrinsics guide:
- _mm256_stream_load_si256 takes `__m256i const *'

a5efe3a66b [DarwinDriver] Reapply: Use -lto_library to specify the path for libLTO.dylib
Reapply r248935.

Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.

However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

195b3b0074 [analyzer] Add TK_EntireMemSpace invalidation trait.
This commit supports Sean Eveson's work on loop widening. It is NFC for now.
It adds a new TK_EntireMemSpace invalidation trait that, when applied to a
MemSpaceRegion, indicates that the entire memory space should be invalidated.

Clients can add this trait before invalidating. For example:

RegionAndSymbolInvalidationTraits ITraits;
ITraits.setTrait(MRMgr.getStackLocalsRegion(STC),
                 RegionAndSymbolInvalidationTraits::TK_EntireMemSpace);

This commit updates the existing logic invalidating global memspace regions for
calls to additionally handle arbitrary memspaces. When generating initial
clusters during cluster analysis we now add a cluster to the worklist if
the memspace for its base is marked with TK_EntireMemSpace.

This also moves the logic for invalidating globals from ClusterAnalysis to
invalidateRegionsWorker so that it is not shared with removeDeadBindingsWorker.

There are no explicit tests with this patch -- but when applied to Sean's patch
for loop widening in http://reviews.llvm.org/D12358 and after updating his code
to set the trait, the failing tests in that patch now pass.

e12597cc23 [clang-format] Add support of consecutive declarations alignment
This allows clang-format to align identifiers in consecutive
declarations. This is useful for increasing the readability of the code
in the same way the alignment of assignations is.

The code is a slightly modified version of the consecutive assignment
alignment code. Currently only the identifiers are aligned, and there is
no support of alignment of the pointer star or reference symbol.

The patch also solve the issue of alignments not being possible due to
the ColumnLimit for both the existing AlignConsecutiveAligments and the
new AlignConsecutiveDeclarations.

 - Allow static local and global variables (OpenCL2.0 s6.8 and s6.5.1).

 - Improve diagnostics of allowed ASes for variables in different scopes:
(i) Global or static local variables have to be in global
or constant ASes (OpenCL1.2 s6.5, OpenCL2.0 s6.5.1);
(ii) Non-kernel function variables can't be declared in local

48fefa3724 Fix FunctionParmPackExpr::Create() to take a ParmVarDecl* array.
FunctionParmPackExpr actually stores an array of ParmVarDecl* (and
accessors return that). But, the FunctionParmPackExpr::Create()
constructor accepted an array of Decl *s instead.

It was easy for this mismatch to occur without any obvious sign of
something wrong, since both the store and the access used independent
'reinterpet_cast<XX>(this+1)' calls.

a91de375f2 Promote a warning on ill-formed code (redeclaration missing an exception
specification) to an error. No compiler other than Clang seems to allow this,
and it doesn't seem like a useful thing to accept as an extension in general.

The current behavior was added for PR5957, where the problem was specifically
related to mismatches of the exception specification on the implicitly-declared
global operator new and delete. To retain that workaround, we downgrade the
error to an ExtWarn when the declaration is of a replaceable global allocation
function.

Now that this is an error, stop trying (and failing) to recover from a missing
computed noexcept specification. That recovery didn't work, and led to crashes
in code like the added testcase.

Parsing and sema analysis for 'simd' clause in 'ordered' directive.
Description
If the simd clause is specified, the ordered regions encountered by any thread will use only a single SIMD lane to execute the ordered
regions in the order of the loop iterations.
Restrictions
An ordered construct with the simd clause is the only OpenMP construct that can appear in the simd region

74a7c5dc16 The Clang gcc-compatible driver (clang/tools/driver/driver.cpp) has some
logic to select an alternate target based on the executable it was
called as. For instance, if you symlink i686-linux-android-gcc to clang
and invoke it, the driver will act as though it were called with another
argument ("-target i686-linux-android"). This leads to visible effects
even in syntax-only compilations (like the ANDROID preprocessor symbol
being defined).

This behavior is not replicated for tool invocations--for instance,
clang::createInvocationFromCommandLine will not choose an alternate
target based on ArgList[0]. This means that configurations stored in
compilation databases aren't accurately replayed.

This patch separates the logic for selecting a mode flag and target from
the executable name into a new member function on ToolChain. It should
have no functional effects (but will allow other code to reuse the
target/mode selection logic).

346265e3bc [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.
OpenMP 4.1 extends format of '#pragma omp ordered'. It adds 3 additional clauses: 'threads', 'simd' and 'depend'.
If no clause is specified, the ordered construct behaves as if the threads clause had been specified. If the threads clause is specified, the threads in the team executing the loop region execute ordered regions sequentially in the order of the loop iterations.
The loop region to which an ordered region without any clause or with a threads clause binds must have an ordered clause without the parameter specified on the corresponding loop directive.

0da2e93345 [analyzer] When memcpy'ing into a fixed-size array, do not invalidate entire region.
Change the analyzer's modeling of memcpy to be more precise when copying into fixed-size
array fields. With this change, instead of invalidating the entire containing region the
analyzer now invalidates only offsets for the array itself when it can show that the
memcpy stays within the bounds of the array.

This addresses false positive memory leak warnings of the kind reported by
krzysztof in https://llvm.org/bugs/show_bug.cgi?id=22954

(This is the second attempt, now with assertion failures resolved.)
