[AArch64] Prefer FPRs over GPRs for INSR
INSR of GPRs involves a cross-file move while INSR of FPRs doesn't.
We should therefore disparage the GPR version relative to the FPR
version.
The patch also adds MOVPRFX handling, but this is only tested
properly by the ACLE.

gcc/
* config/aarch64/aarch64-sve.md (vec_shl_insert_<mode>): Add
MOVPRFX alternatives. Make the GPR alternatives more expensive
than the FPR ones.
gcc/testsuite/
* gcc.target/aarch64/sve/init_12.c: Expect w1 to be moved into
a temporary FPR.
