Just like other insns having byte and word forms, these can also make
use of the W modifier, which at the same time allows simplifying some
other code a little bit.
Various moves come in load and store forms, and just like on the GPR
and FPU sides there would better be only one pattern. In some cases this
is not feasible because the opcodes are too different, but quite a few
cases follow a similar standard scheme. Introduce Opcode_SIMD_FloatD and
Opcode_SIMD_IntD, generalize handling in operand_size_match() (reverse
operand handling there simply needs to match "straight" operand one),
and fix a long standing, but so far only latent bug with when to zap
found_reverse_match.
Also once again drop IgnoreSize where pointlessly applied to templates
touched anyway as well as *word when redundant with Reg*.

Partial write %PSR (PWRPSR) is a SPARC V8e option that allows the WRPSR
instruction to only affect the %PSR.ET field. When available it is enabled
by setting the rd field of the WRPSR instruction to a value other than 0.
For Leon processors with support for partial write %PSR (currently GR740
and GR716) the rd value must be 1.

Most optional operands to powerpc instructions use a default value of
zero, but there are a few exceptions. Those have been handled by
PPC_OPERAND_OPTIONAL_VALUE and an entry in the powerpc_operands table
for the default value, smuggled in the shift field. This patch
changes that to using the operand extract function to provide non-zero
defaults.
I've also moved the code determining whether optional operands are
provided or omitted, to the point the first optional operand is seen,
and allowed for the possibility of optional base register operands
in a future patch.
The patch does change the error you get on invalid assembly like
ld 3,4
You'll now see "missing operand" rather than
"syntax error; end of line, expected `('".
