[AArch64] Fix aarch64_ira_change_pseudo_allocno_class
A recent commit removing '*' from the md files caused a large regression in
h264ref. It turns out aarch64_ira_change_pseudo_allocno_class is no longer
effective after the SVE changes, and the combination results in the regression.
This patch fixes it by explicitly checking for a subset of GENERAL_REGS and
FP_REGS. Add a missing ? to aarch64_get_lane to fix a failure in the testsuite.
gcc/
* config/aarch64/aarch64.c (aarch64_ira_change_pseudo_allocno_class):
Check for subset of GENERAL_REGS and FP_REGS.
* config/aarch64/aarch64-simd.md (aarch64_get_lane): Increase cost of
r=w alternative.
