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 Signed-off-by: Maciej W.
