the instruction BBI points to.

c66a43e2b0 Add support for modeling whether or not the processor has support for 
conditional moves as a subtarget feature.  This is the easy part of 
PR4841.

1f08c79edc fix PR4848 an infinite loop when indexing down through a recursive gep 
and we get the original pointer type.  This doesn't mean that we're
at the first pointer being indexed.  Correct the predicate.

return a vector of i1, not i1 itself.

3b7954c9bf Don't force the triple or data layout in this test. We just have to get them 
from the host and hope that works.

8dfa4a30bf Fixed the asmstrings for 8-bit, 16-bit, and 32-bit ADD %rAX, imm instructions. 
Added a 64-bit ADD %RAX, imm32 instruction.
Added all 4 forms for AND %rAX, imm and CMP %rAX, imm.

24b0f4a60e Fix PR4845: r77946 completely broke x86_64 Darwin (or any situation where the 
desired triplet is a sub-target, e.g. thumbv7 vs. arm host). Reverting the
patch isn't quite right either since the previous behavior does not allow the
triplet to be overridden with -march.
