f0c267e6e0 Provide half floating point support as a storage only type. 
Lack of half FP was a regression compared to llvm-gcc.

7cdf948601 Recommit: 
Start handling debug line and scope information better:

    Migrate most of the location setting within the larger API in CGDebugInfo and
    update a lot of callers.
    Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
    and replace it with DILexicalBlockFile usage.

    Finishes off the rest of rdar://10246360

after fixing a few bugs that were exposed in gdb testsuite testing.

caf3390d44 Constant expression evaluation refactoring: 
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert
   behaviour.
 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

e0dc7cb2e2 Apparently getPtrToInt() takes an explicit type parameter to allow you to generate invalid bitcode, not so that it can actually produce a value of this type. This should fix PR11085.

c168e50722 Free 'TheTargetCodeGenInfo' in the class CodeGenModule. This looks like an obvious memory leak that was reported from LLDB devs. The comment indicates the leak is deliberate, but I have no idea why this needs to be so. Please comment/revert if you know otherwise.

0710e551ef Record layout requires not just a definition, but a complete

aggressively emit the IR translation of a record during its
own definition.  Fixes PR10912.

0dfb889575 Support for C1x _Atomic specifier (see testcase). This is primarily being committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic.

fab289a47d When constructing debug information for synthesized variables for the 
non-fragile ABI we may not be able to lay out the type and the debugger
would ignore us even if we did put in the offset. Go ahead and just
put any value there and don't look up the offset since it may not exist.

b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl. 
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.

9b0a7cea0f Make -fobjc-nonfragile-abi the -cc1 default, since it's the 
increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.

Most, though, it involved a perl script to translate a ton
of test cases.

Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.
