Summary:
Calls to @llvm.experimental.deoptimize are expected to "never execute",
so optimize them as such.

constructor's definition is in an implementation block.
Without this commit, ptr doesn't get initialized to null in the
following code:
struct S {
S();
void *ptr = nullptr;
};
@implementation I
S::S() {}

There's currently no raw_ostream &operator<<(SimpleValueType); provided by LLVM. It could be added by refactoring utils/TableGen/CodeGenTarget.cpp:getEnumName, but that's much more work than fixing the build.

Also,
- Skip pass if machine module does not have debug info
- Minor comment changes
- Added test

The race boiled down to this:
If a test worker queue is able to run the test inferior and
clean up before the dosep.py listener socket is spun up, and
the worker queue is the last one (as would be the case when
there's only one test rerunning in the rerun queue), then
the test suite will exit the main loop before having a chance
to process any test events coming from the test inferior or
the worker queue job control.
I found this race to be far more likely on fast hardware.
Our Linux CI is one such example. While it will show
up primarily during meta test events generated by
a worker thread when a test inferior times out or
exits with an exceptional exit (e.g. seg fault), it only
requires that the OS takes longer to hook up the
listener socket than it takes for the final test inferior
and worker thread to shut down.

The root of the problem was that findMainViewFileID(File, Function)
could return some ID for any given file, even though that file
was not the main file for that function.
This patch ensures that the result of this function is conformed
with the result of findMainViewFileID(Function).
This commit reapplies r266436, which was reverted by r266458,
with the .covmapping file serialized in v1 format.

This reverts commit r266477.
This commit introduces cyclic dependency. This commit has "Analysis" depend on "ProfileData",
while "ProfileData" depends on "Object", which depends on "BitCode", which
depends on "Analysis".

Order should match the sp3 syntax, where destination (simm16 denoting the hwreg) is coming first.

Three problems:
1. <future> can't be easily used. If you must use it, see
include/Support/ThreadPool.h for how.
2. constexpr problems, even after 266588.
3. Move assignment operators can't be defaulted in MSVC2013.

Prior to this patch, setting LIBCXXABI_LIBDIR_SUFFIX would confuse the
check-libcxxabi target. libc++abi.* would get output to lib instead of
lib${LIBCXXABI_LIBDIR_SUFFIX}, but the tests would look in the suffixed
directory.
Now, we match what libcxx does, and set the CMAKE_*_OUTPUT_DIRECTORY to the
LIBRARY_DIR.

Summary:
When clang is given -save-temps or -via-file-asm, any inline assembly in
the source is parsed twice. Once by the compiler, and again by the
assembler. We must take care to ensure that this doesn't lead to
double-filling delay slots.

This requires adding a few more expression types, but is already a small
simplification. Having Writer.cpp know the exact expression will also
allow further simplifications.
llvm-svn: 266604
Summary:
This will allows us to eliminate some magic numbers from the offset operand of
branch instructions in favour of symbols and makes it possible to avoid
double-filling delay slots when clang is given -save-temps.
parseDirectiveCpRestore() is calling isIntegratedAssemblerRequired() for the
moment since correctly pushing the generation of these instructions into the
ELF target streamer is tricky enough to warrant a separate patch.
