John McCall d25db7ed0f Grab-bag of bit-field fixes:
- References to ObjC bit-field ivars are bit-field lvalues;
    fixes rdar://13794269, which got me started down this.
  - Introduce Expr::refersToBitField, switch a couple users to
    it where semantically important, and comment the difference
    between this and the existing API.
  - Discourage Expr::getBitField by making it a bit longer and
    less general-sounding.
  - Lock down on const_casts of bit-field gl-values until we
    hear back from the committee as to whether they're allowed.

Eli Friedman 609ada27ce Silliness with commas, as reported at http://blog.regehr.org/archives/558 . As it turns out, this is my fault for not noticing this was an issue when I was looking at this a long time ago. :(

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor 71235ecb7f When determining whether an expression refers to a bit-field, look
into the left-hand side of an assignment expression. This completes
most of PR3500; the only remaining part is to deal with the
GCC-specific implementation-defined behavior for "unsigned long" (and
other) bit-fields.

Douglas Gregor d2c2d172da Fix bitfield promotions in several more cases. We don't seem to work hard enough at determining whether an expression is a bitfield or not, yet.

Douglas Gregor 8145742349 Partial fix for PR3310, concerning type-checking for tentative
definitions. We were rejecting tentative definitions of incomplete
(which is bad), and now we don't.

This fix is partial because we don't do the end-of-translation-unit
initialization for tentative definitions that don't ever have any
initializers specified.
