99bd2de619 Fix an issue where LLDB would detect an empty shared cache - which is legitimate albeit suboptimal - and warn about being unable to fetch ObjC class information, even though class data was actually properly loaded from the dynamic hashmap
Only ever warn about missing ObjC runtime class data if one either can't run the expressions to obtain such data, or the total count of classes is below a threshold that makes things sound really suspicious

d9c9da536f Add a default-value bool flag pretty_print to the StructuredData Dump methods.
They will dump pretty-print (indentation, extra whitepsace) by default.  
I'll make a change to ProcessGDBRemote soon so it stops sending JSON strings
to debugserver pretty-printed; it's unnecessary extra bytes being sent between
the two.

This reverts r275782.

The problem with the commit is that it reports an additional "exit (1)" error for every file
containing a failing test, which is far more than I had intended to do. I'll need to come up with
a more fine-grained way of achieving the result.

52bd8012bd [test] Report error when inferior test processes exit with a non-zero code
Summary:
We've run into this problem when the test errored out so early (because it could not connect to
the remote device), that the code in D20193 did not catch the error. This resulted in the test
suite reporting success with 0 tests being run.

This patch makes sure that any non-zero exit code from the inferior process gets reported as an
error. Basically I expand the concept of "exceptional exits", which was previously being used for
signals to cover these cases as well.

97be487728 Implement GetMemoryRegions() for Windows Minidumps and live processes.
Summary:
This patch fills in the implementation of GetMemoryRegions() on the Windows live process and minidump implementations of lldb_private::Process (ProcessWindowsLive::GetMemoryRegionInfo and ProcessWinMiniDump::Impl::GetMemoryRegionInfo.) The GetMemoryRegions API was added under: http://reviews.llvm.org/D20565

The existing Windows implementations didn’t fill in the start and end addresses within MemoryRegionInfo. This patch fixes that and adds support for the new mapped flag on MemoryRegionInfo that says whether a memory range is mapped into the process address space or not.

The behaviour of both live and core implementations should match the behaviour documented on Process::GetMemoryRegionInfo (in Process.h) which in turn should match the behaviour of the qMemoryRegionInfo query documented in lldb-gdb-remote.txt.

5fe4d141e0 Refactor (with some rewriting) the DynamicLoaderMacOSX plugin into
a base class and a derived class, with the derived class containing
the methods specific to reading dyld's all_image_infos, dyld's
method of specifying images that have been loaded or unloaded, the
place where we put a breakpoint in dyld to get notified about newly
loaded or unloaded images.

This is in preparation for a second derived class which will use
some alternate methods for getting this information; that will be
a separate commit in the next few days.

There's a couple of ivars that should probably be in the derived
DyanmicLoaderMacOSX class instead of the base DynamicLoaderDarwin
class (m_dyld_image_infos, m_dyld_image_infos_stop_id).  I don't
think I'll need to use these in the new derived class - I'll 
move them down to DynamicLoaderMacOSX if it works out that way;
it'll simplify locking if I can do that.

240414dc95 Editing multi-line content in a terminal environment involves a lot of
trade-offs. When LLDB's multi-line editing support was first introduced
for expressions / REPL contexts the behavior was as follows:

* The Return key is treated as a line-break except at the end of the input
  buffer, where a completeness test is applied

This worked well enough when writing code, and makes it trivial to insert
new lines above code you've already typed. Just use cursor navigation to
move up and type freely. Where it was awkward is that the gesture to insert
a line break and end editing is conflated for most people. Sometimes you
want Return to end the editing session and other times you want to insert
a line break.

This commit changes the behavior as follows:

* The Return key is treated as the end of editing except at the end of the
  input buffer, where a completeness test is applied

* The Meta+Return sequence is always treated as a line break. This is
  consistent with conventions in Facebook and elsewhere since
  Alt/Option+Return is often mapped to Meta+Return. The unfortunate
  exception is on macOS where this *can* be the case, but isn't by
  default. Sigh.

Note that by design both before and after the patch pasting a Return
character always introduces a line break.

6234a5c863 Centralize the way symbol and functions are looked up by making a Module::LookupInfo class that does all of the heavy lifting.
Background: symbols and functions can be looked up by full mangled name and by basename. SymbolFile and ObjectFile are expected to be able to do the lookups based on full mangled name or by basename, so when the user types something that is incomplete, we must be able to look it up efficiently. For example the user types "a:🅱️:c" as a symbol to set a breakpoint on, we will break this down into a 'lookup "c"' and then weed out N matches down to just the ones that match "a:🅱️:c". Previously this was done manaully in many functions by calling Module::PrepareForFunctionNameLookup(...) and then doing the lookup and manually pruning the results down afterward with duplicated code. Now all places use Module::LookupInfo to do the work in one place.

This allowed me to fix the name lookups to look for "func" with eFunctionNameTypeFull as the "name_type_mask", and correctly weed the results:

"func", "func()", "func(int)", "a::func()", "b::func()", and "a:🅱️:func()" down to just "func", "func()", "func(int)". Previously we would have set 6 breakpoints, now we correctly set just 3. This also extends to the expression parser when it looks up names for functions it needs to not get multiple results so we can call the correct function.

1ee89eb8d9 Add "support" for DW_CFA_GNU_args_size to the unwinder
Summary:
This adds the knowledge of the DW_CFA_GNU_args_size instruction to the eh_frame parsing code.
Right now it is ignored as I am unsure how is it supposed to be handled, but now we are at least
able to parse the rest of the FDE containing this instruction.

I also add a fix for a bug which was exposed by this instruction. Namely, a mismatched sequence
of remember/restore instructions in the input could cause us to pop an empty stack and crash. Now
we just log the error and ignore the offending instruction.

dc15f1d7b8 Fix a race on process exit
Summary:
Process::SetExitStatus was popping the process io handler and resetting m_process_input_reader
shared pointer, which is not a safe thing to do as the function is called asynchronously and
other threads may be accessing the member variable. (E.g. if the process terminates really
quickly, the private state thread might only be in the process of pushing the handler on the
stack. Sometimes, this leads to deadlock, as the shared pointer's state gets corrupted by the
concurrent access.

Since the IOHandler will be popped anyway in Process:HandleProcessStateChangedEvent when the
exited event gets processed, doing the same in SetExitStatus seems to be unnecessary.
