[TargetPassConfig] Enable machine verification after miscellaneous pa…

…sses

In a couple of places machine verification was disabled for no apparent
reason, probably just because an "addPass(..., false)" line was cut and
pasted from elsewhere.

After this patch the only remaining place where machine verification is
disabled in the generic TargetPassConfig code, is after addPreEmitPass.
