MIPS/gas: Retain ISA mode bit for labels with .insn annotation
gas/
* config/tc-mips.c (mips_move_labels): Retain ISA mode bit
when moving labels in text segments.
(mips_align): Indicate text mode when aligning labels in
text segments.
* gas/testsuite/gas/mips/insn-isa-mode.d: New test.
* gas/testsuite/gas/mips/insn-isa-mode.s: New test source.
* gas/testsuite/gas/mips/mips.exp: Run the new test.
