Log:
ARM Thumb blx instruction fixup has same data range as bl.

These fixups are handled poorly in general, and should have a single
contiguous range of bits per fixup type, but that's not how they're
currently organized, so for now in complex ones like for blx, we just tell the
emitter it's OK for the fixup to munge any bit it wants.
