bc4cf8d5b1 For better or worse, load from i1 is assumed to be zero extended. Do not 
form a load from i1 from larger loads that may not be zext'd.

3da59db637 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

functionality in the AsmParser, its just plumbing for future changes.
