Add initial support for fast-isel of the [SU]ADDO intrinsics. It isn't
complete. For instance, it lowers the common case into this less-than-optimal
code:
addl %ecx, %eax
seto %cl
testb %cl, %cl
jne LBB1_2 ## overflow
instead of:
addl %ecx, %eax
jo LBB1_2 ## overflow
That will come in a future commit.
