gcc/
* config/aarch64/aarch64.md (fccmp): Change insn type.
(fccmpe): Likewise.
* config/aarch64/thunderx.md (thunderx_fcmp): Add "fccmp{s,d}" types.
* config/arm/cortex-a53.md (cortex_a53_fpalu): Likewise.
* config/arm/cortex-a57.md (cortex_a57_fp_cmp): Likewise.
* config/arm/xgene1.md (xgene1_fcmp): Likewise.
* config/arm/exynos-m1.md (exynos_m1_fp_ccmp): New insn reservation.
* config/arm/types.md (fccmps): Add new insn type.
(fccmpd): Likewise.
