Remove *FP uses from all non-floating-point instructions. Unite 32- and 64-bit forms of movsx, movzx, and movd. Adjust floating point operations for the above changes to the *FP macros.

More instructions will need to be added to this group. (putop): Handle new macro chars 'C' (short/long suffix selector), 'I' (Intel mode override for following macro char), and 'J' (for adding the 'l' prefix to far branches in AT&T mode). When an alternative was specified in the template, honor macro character when specified for Intel mode. (OP_E): Handle new *_mode values. Correct pointer specifications for memory operands.

alternative of a relaxable macro. Remove redundant check for
branch relaxation. If generating a normal insn, and there
is not enough room in the current frag, call relax_close_frag()
to close it. Update mips_relax.sizes[]. Emit fixups for the
second version of a relaxable macro. Record the first relaxable
fixup in mips_relax. Remove tc_gen_reloc workaround.

in the same way as in append_insn.
(mips16_macro_build): Remove "place" argument.

when generating the second version of a relaxable macro.

tc_gen_reloc workarounds.
