[AArch64] Force __builtin_aarch64_fp[sc]r argument into a REG
The testcase triggered an ICE because the builtin expansion
code passed the output of expand_normal directly to the SET_FP[SC]R
generator, without forcing it into a register first.
gcc/
* config/aarch64/aarch64-builtins.c (aarch64_expand_builtin): Force
__builtin_aarch64_fp[sc]r arguments into a register.
gcc/testsuite/
* gcc.target/aarch64/fpcr_fpsr_1.c: New file.
