8205972a5a Fix a regression in the last patch. When constructing a BitMask, be careful
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.

7808dcba05 Provide an isPowerOf2ByteWidth method for the IntegerType class. This will
mostly be used by back ends that wish to distinguish between integer types
that fit evenly within a natural integer type and those that don't.

23e28836ed Two changes:
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.

a10dc506c0 For PR1028:
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:

5032e5a613 * Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.
