Sean Callanan 77a1fd3f45 Moved byte-size computation out of a 
startDefinition() ... endDefinition() block,
preventing crashes where the byte size of a
not-yet-complete type was being computed.

Benjamin Kramer 5e8636f36e Just drop the bitfield from ExtProtoInfo, this struct isn't even heap allocated so it doesn't hurt. 
MSVC < 10 still has the signed enum bitfield bug, making the top bit unusable.

Sean Callanan 8b66598652 Harden the checks on the type returned from the 
AST importer because we're seeing occasional
crashes.

Greg Clayton ea5e0cc320 Enabled the PlatformLinux and PlatforFreeBSD on MacOSX so they can be used 
and also so we don't break them with our code changes.

The _only_ plug-ins that should be #ifdef'ed out and not compiled in LLDB
are those that only work when running natively on the host system.

This fixed bot the PlatformLinux and PlatformFreeBSD build breakages that
were due to ModuleSpec changes.

Greg Clayton d10a038cf3 Added the POSIX-DYLD as a plug-in in the darwin build in the Xcode project 
so that we don't break it with code changes. 

After doing this I was able to fix the POSIX-DYLD plug-in so that it builds
after recent ModuleSpec changes.

Chad Rosier d6a56db7b6 Test case for r151429/r151430, which ensures llvm.lifetime intrinsics are not 
being emitted at -O0, but are emitted when optimizations are enabled.

Jakob Stoklund Olesen 5aafb56dc0 Update machine code verifier. 
After the SlotIndex slot names were updated, it is possible to apply
stricter checks to live intervals.

Also treat bundles as bags of operands when checking live intervals.

Kevin Enderby 1489b523c3 Fix the symbolic operand added for the C disassmbler API for the ARM bl 
thumb instruction.  The PC adjustment is +4 in Thumb mode and +8 in ARM mode.

Jakob Stoklund Olesen 1f152baef8 Add a MachineOperand iterator class. 
The MIOperands iterator can visit operands on a single instruction, or
all operands in a bundle.  This simplifies code like the register
allocator that treats bundles as a set of operands.

Alexander Potapenko 7e07f56811 Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports. 
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.

Duncan Sands 1be25a78f7 The value numbering function is recursive, so it is possible for multiple new 
value numbers to be assigned when calculating any particular value number.
Enhance the logic that detects new value numbers to take this into account,
for a tiny compile time speedup.  Fix a comment typo while there.

Duncan Sands 27f459519d When performing a conditional branch depending on the value of a comparison 
%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and
with "false" under the false edge.  This change enhances this to replace the
negated compare (A!=B) with "false" under the true edge and "true" under the
false edge.  Reported to improve perlbench results by 1%.

Richard Smith 9a6403a9de Half of PR12088: parse braced-init-lists on the RHS of assignment operators. 
If the assignment operator is a scalar type, we continue to incorrectly reject
the initializer, but semantic analysis (and codegen) is correct for overloaded
operators.

Benjamin Kramer b73f76b642 Reorder members to save padding. 
There's more potential here, but these Exprs aren't used that often so I don't feel like doing heroic bit packing right now.
