Ulrich Weigand edc6a13992 [PowerPC] Fix PR 21652 - copy st_other bits on symbol assignment
When processing an assignment in the integrated assembler that sets
a symbol to the value of another symbol, we need to copy the st_other
bits that encode the local entry point offset.

Modeled after MipsTargetELFStreamer::emitAssignment handling of the
ELF::STO_MIPS_MICROMIPS flag.
