This patch adds new function libc_feholdsetround_noex_aarch64_ctx, enabling
further optimization. libc_feholdsetround_aarch64_ctx now only needs to read the FPCR in the typical case, avoiding a redundant FPSR read. Performance results show a good improvement (5-10% on sin()) on cores with expensive FPCR/FPSR instructions.
