Complement commit 7361da2c95 ("Add support for MIPS R6.") and fix
internal errors like:
foo.s: Assembler messages:
foo.s: Internal error!
Assertion failure in md_apply_fix at .../gas/config/tc-mips.c:15028.
Please report this bug.

R6 code fragments wrapped into ISA override blocks embedded within code
otherwise assembled for an older ISA.
