526ab47a55 Restore r142914 and r142915, now with missing file and apparent 
GCC compiler workaround.

9a8f13961c Revert r142914 and r142915, due to possibly missing file. 
r142914: "Introduce a placeholder type for "pseudo object""
r142915: "Pull the pseudo-object stuff into its own file."

c4a2d3259f Introduce a placeholder type for "pseudo object" 
expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

deb4a2be67 Implement support for dependent Microsoft __if_exists/__if_not_exists 
statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".

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.

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.
