MIPS: Apply `.insn' to fixup labels throughout
Fix the issue with the ISA bit being lost in fixups that jump to labels
placed just before a section switch. Such a switch leads to the ISA bit
being lost, because GAS concludes there is no code that follows and
therefore the label refers to data. Use the `.insn' pseudo-op to
convince the tool this is not the case.
This lack of label annotation leads to microMIPS compilation errors
like:
mips-linux-gnu-ld: arch/mips/built-in.o: .fixup+0x3b8: Unsupported jump between ISA modes; consider recompiling with interlinking enabled.
mips-linux-gnu-ld: final link failed: Bad value
