[RISCV] Move DebugLoc Copy into CompressInstEmitter
Summary:
This copy ensures that debug location information is kept for
compressed instructions. There are places where both compressInstruction and
uncompressInstruction are called that were not doing this copy, discarding some
debug info.
This change merely moves the copy into the generated file, so you cannot forget
to copy the location over when compressing or uncompressing.
