Removing a bit of custom parsing functionality used by the thread safety analysis APIs. Now using tablegen to determine whether an attribute's arguments should be parsed in an unevaluated context instead of relying on a separate, hard-coded list of attributes.

Revert "Disable LeakSanitizer in TableGen binaries, see PR18325"

To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.

See the list discussion for details.

This reverts commit r198858.

Have attribute 'objc_precise_lifetime' suppress -Wunused.

Fixes <rdar://problem/15596883>

In ARC, __attribute__((objc_precise_lifetime)) guarantees that the
object stored in it will survive to the end of the variable's formal
lifetime.  It is therefore useful even if it completely unused.

Unfortunately, I have no idea how to test this code.

Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out. This is necessary so that __has_attribute can eventually determine whether a parsed attribute applies to the given target or not.

__has_attribute now understands target-specific attributes. So when you ask whether an ARM target has the "interrupt" attribute, it will return true for ARM and MSP430 targets, and false for others.

[ms-abi] Fixing CGRecordLayoutBuilder w.r.t. MS NonVirutalBase Layout


The MS abi lays out *all* non-virtual bases with leading vfptrs before 
laying out non-virutal bases without vfptrs.  This guarantees that the 
primary base is laid out first.  r198818 fixed RecordLayoutBuilder to 
produce compatiable layouts.  This patch fixes CGRecordLayoutBuilder to 
be able to consume those layouts and produce meaningful output without 
tripping any asserts about assumed incoming layout.

A test case is included that shows CGRecordLayoutBuilder in fact 
produces output in the compatiable order.

[ms-abi] Handle __declspec(align) on bitfields "properly"

__declspec(align), when applied to bitfields affects their perferred 
alignment instead of their required alignment.  We don't know why.  
Also, #pragma pack(n) turns packing *off* if n is greater than the 
pointer size.  This is now observable because of the impact of 
declspec(align) on bitfields.
