2219ef0b68 Minor cleanup, mostly reindenting. Remove one helper function that just called 
the other helper functions, since we already differentiated the cases it was
testing between. No functionality change.

7b553f1b19 Rename Expr::Evaluate to Expr::EvaluateAsRValue to make it clear that it will 
implicitly perform an lvalue-to-rvalue conversion if used on an lvalue
expression. Also improve the documentation of Expr::Evaluate* to indicate which
of them will accept expressions with side-effects.

ba743b75cb Take DW_AT_comp_dir from $PWD when it's present and starts with a '/'. This is 
closer to what GCC does, except that GCC also checks that the inodes for $PWD
and '.' match.

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.

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.

point in the code. Ensures that we don't miss any places and the
check is reasonably cheap.

ASTUnit build the ASTContext as needed when loading an AST file,
