rs6000: Remove the ancient mfcr peepholes
These peepholes replace two mfcr;mask sequences by one mfcr;mask;mask
sequence. On modern cpus, the original mfcr's were actually mfocrf,
but the new insn is an actual heavy-weight mfcr. This is very bad
for performance.
The comment says there is a three cycle delay between two consecutive
mfcr insns. This may have been true on rios, and it's true on 604,
but on 603, 750, 7400 it is just a single cycle (on 7450 it is two).
This is also a define_peephole, and we should get rid of those.
So this patch just removes the peepholes; the benefit is marginal at
best, and it so very hurts in other cases.

Update TARGET_FUNCTION_INCOMING_ARG documentation
On x86, interrupt handlers are only called by processors which push
interrupt data onto stack at the address where the normal return address
is. Since interrupt handlers must access interrupt data via pointers so
that they can update interrupt data, the pointer argument is passed as
"argument pointer - word".
TARGET_FUNCTION_INCOMING_ARG defines how callee sees its argument.
Normally it returns REG, NULL, or CONST_INT. This patch adds arbitrary
address computation based on hard register, which can be forced into a
register, to the list.
When copying an incoming argument onto stack, assign_parm_setup_stack
has:
if (argument in memory)
copy argument in memory to stack
else
move argument to stack
Since an arbitrary address computation may be passed as an argument, we
change it to:
if (argument in memory)
copy argument in memory to stack
else
{
if (argument isn't in register)
force argument into a register
move argument to stack
}
* function.c (assign_parm_setup_stack): Force source into a
register if needed.
