Make GNUInline consistent with whether we use traditional GNU inline semantics.
Previously we were setting LangOptions::GNUInline (which controls whether we
use traditional GNU inline semantics) if the language did not have the C99
feature flag set. The trouble with this is that C++ family languages also
do not have that flag set, so we ended up setting this flag in C++ modes
(and working around it in a few places downstream by also checking CPlusPlus).
The fix is to check whether the C89 flag is set for the target language,
rather than whether the C99 flag is cleared. This also lets us remove most
CPlusPlus checks. We continue to test CPlusPlus when deciding whether to
pre-define the __GNUC_GNU_INLINE__ macro for consistency with GCC.
There is a change in semantics in two other places
where we weren't checking both CPlusPlus and GNUInline
(FunctionDecl::doesDeclarationForceExternallyVisibleDefinition and
FunctionDecl::isInlineDefinitionExternallyVisible), but this change seems to
put us back into line with GCC's semantics (test case: test/CodeGen/inline.c).
While at it, forbid -fgnu89-inline in C++ modes, as GCC doesn't support it,
it didn't have any effect before, and supporting it just makes things more
complicated.

ARM: refactor optimizeThumb2JumpTables.
The previous logic mixed 2 separate questions:
+ Can we form a TBB/TBH instruction?
+ Can we remove the jump-table calculation before it?
It then performed a bunch of random tests on the instructions earlier in the
basic block, which were probably sufficient to answer 2 but only because of the
very limited ways in which a t2BR_JT can actually be created.
For example there's no reason to expect the LeaInst to define the same base
register as the following indexing calulation. In practice this means we might
have missed opportunities to form TBB/TBH, in theory you could end up
misidentifying a sequence and removing the wrong LEA:
%R1 = t2LEApcrelJT ...
%R2 = t2LEApcrelJT ...
<... using and killing %R2 ...>
%R2 = t2ADDr %R1, $Ridx
Before we would have looked for an LEA defining %R2 and found the wrong one. We
just got lucky that jump table setup was (almost?) always confined to a single
basic block and there was only one jump table per block.

Add function entry counts from sample profiles.
This patch uses the new function profile metadata "function_entry_count"

In a sampling profile, the total samples collected at the function entry

Add function entry count metadata.
Summary:
This adds three Function methods to handle function entry counts:
setEntryCount() and getEntryCount().
Entry counts are stored under the MD_prof metadata node with the name
"function_entry_count". They are unsigned 64 bit values set by profilers
(instrumentation and sample profiler changes coming up).
Added documentation for new profile metadata and tests.

Remote Non-Stop Support
Summary:
This patch is the beginnings of support for Non-stop mode in the remote protocol. Letting a user examine stopped threads, while other threads execute freely.
Non-stop mode is enabled using the setting target.non-stop-mode, which sends a QNonStop packet when establishing the remote connection.
Changes are also made to treat the '?' stop reply packet differently in non-stop mode, according to spec https://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Non_002dStop.html#Remote-Non_002dStop.
A setting for querying the remote for default thread on setup is also included.
Handling of '%' async notification packets will be added next.
