Use do+while instead of while for loops which obviously have a
...
non-zero trip count. Use SmallVector's pop_back_val().

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

Eliminate the 'AddMaskingAnd' transformation, it is redundant with this

to try this hard for simple associative optimizations. Next
