[MIPS, committed] Replace DEXT and DINS macros

- Subject: [MIPS, committed] Replace DEXT and DINS macros
DEXT and DINS were handled as macros that expand into one of D{EXT,INS}{,U,M}.
This patch instead handles them like the Octeon CINS instructions, with DEXT
and DINS aliases for each of the three underlying architectural instructions.
I put the aliases first because I think that's more user-friendly[*].
This showed up a bug: the "real" DEXT instruction should use the 64-bit
operand +H rather than the 32-bit operand +C. It also makes the errors
for EXT and DEXT consistent again (after the previous set_insn_error*
patches).
[*] I'd actually like to do the same for other instructions too. E.g. it's
been a long-standing pet peeve that "dsll $4,$5,33" is disassembled as
"dsll32 $4,$5,0x1". The original "dsll $4,$5,33" seems more user-friendly.
Any thoughts/objections?
We could have a disassembly option to ignore aliases (probably by
picking the last match rather than first). I'm unlikely to do that
myself but would be happy to review a patch that did. :-)
Tested on various targets and applied.
Richard
include/opcode/
* mips.h (M_DEXT, M_DINS): Delete.
opcodes/
* micromips-opc.c (micromips_opcodes): Replace "dext" and "dins"
macro entries with "dextm", "dextu", "dinsm" and "dinsu" aliases.
Use +H rather than +C for the real "dext".
* mips-opc.c (mips_builtin_opcodes): Likewise.
gas/
* config/tc-mips.c (report_bad_range, report_bad_field): Delete.
(macro): Remove M_DEXT and M_DINS handling.
gas/testsuite/
* gas/mips/ext-ill.l, gas/mips/mips64r2-ill.l: Expect DEXT and DINS
error messages to have the same form as the EXT and INS ones.
* gas/mips/micromips-insn32.d, gas/mips/micromips-noinsn32.d,
gas/mips/micromips-trap.d, gas/mips/micromips.d,
gas/mips/micromips@mips64r2.d, gas/mips/mips64r2.d: Expect
"dext" and "dins" instead of "dextm", "dextu", "dinsm" and "dinsu".
