rs6000: Properly handle LE index munging in vec_shr (PR94710)

The PR shows the compiler crashing with -mvsx -mlittle -O0.  This turns
out to be caused by a failure to make of the higher bits in an index
endian conversion.

Worked around for 8.5 in r8-10491-gb3a45adc90bbbdf7a62e9ff301b32f43ba93cdad and
for 9.4+ by the above commit.

Shortcut identity VEC_PERM expansion [PR94710]

This PR is about the rs6000 backend emitting wrong assembly
for whole vector shift by 0, and while I think it is desirable
to fix the backend, I don't see a point why the expander should
try to emit that, whole vector shift by 0 is identity, we can just
return the operand.

* optabs.c (expand_vec_perm_const): For shift_amt const0_rtx
just return v2.
