Use do+while instead of while for loops which obviously have a

non-zero trip count. Use SmallVector's pop_back_val().

split and/or/xor out into one overly-large (2000LOC) file. However, I think

it does make sense to keep them together, at least for now.

dyn_castNotVal in the X+~X transform. dyn_castNotVal is

Eliminate the 'AddMaskingAnd' transformation, it is redundant with this
more general code right below it:

that got instantiated. There is no reason for instcombine
to try this hard for simple associative optimizations. Next
up, eliminate the template completely.
