Douglas Gregor 0be628ff64 Fix a thinko that caused us not to compute __builtin_offset as a
constant expression in C.

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).

Eli Friedman 64fc3c68e5 Fix for PR4079: make sure to construct the member expressions for
offsetof correctly in the presence of anonymous structs/unions.

This could definitely use some cleanup, but I don't really want to mess 
with the anonymous union/struct code.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Eli Friedman 988a16b9b8 Change the AST generated for offsetof a bit so that it looks like a
normal expression, and change Evaluate and IRGen to evaluate it like a 
normal expression.  This simplifies the code significantly, and fixes 
PR3396.

Chris Lattner 5e4c75f4ef rename -parse-ast-print to -ast-print
rename -parse-ast-dump to -ast-dump
remove -parse-ast, which is redundant with -fsyntax-only

Ted Kremenek 0883fd5817 Removed option "-parse-ast-check" from clang driver. This is now implemented
using "-parse-ast -verify".

Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.

Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.
