  defined externally) requires GOT indirect reference.

transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.

not to overflow 64-bits and end up with a 0 mask. This caused i64 values to
always be stored as 0 with lots of consequential damage to nightly test.

1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are
   acceptable as indices.
2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.

Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond
to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This
allows the CBE to execute these builtins, and fixes:

   test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll
   External/SPEC/CINT2000/176.gcc (CBE)

Ensure the CBE generates calls to GCC builtins for stack_save and
stack_restore when it encounters the corresponding intrinsics.
