John McCall 943fae95f5 Implement __builtin_init_dwarf_reg_size_table and __builtin_dwarf_sp_column 
for 32-bit MIPS processors.  Hat-tip to rdivacky for providing gcc dumps
on this.

Daniel Dunbar 6da1098b4b Sema: Add initial support for '#pragma options align=mac68k'. 
- Docs are fairly sketchy, if someone wants to pore through gcc to look for
   holes I'd appreciate any failing test cases!

Ted Kremenek 15a0abd399 Discard qualifiers for ElementRegions so that a 'const' doesn't change the lookup semantics
