  MC: Optimize emitInstruction and simplify fragment-in-BSS check

Move the FT_Relaxable-in-BSS check from frequently-called
MCObjectStreamer::emitInstruction to MCAssembler::writeSectionData,
along with existing checks for other fragment types. For the uncommon
diagnostics, losing the location information is acceptable.
