Do not specialize IRBuilder to strip names in SROA
Do not specialize IRBuilder to strip names in SROA

Summary:
Following r263086, we are replacing this by a runtime check.
More cleanup will follow on the IRBuilder itself, but I submitted
this patch separately as SROA has a fancy "prefixInserter" class
that needs extra-love.
