    • libgo: don't copy semt into runtime.inc · f30d2091 
          
    https://gcc.gnu.org/PR81449 reports a problem with the definition semt
    in runtime.inc on some systems. Since the C code in libgo/runtime
    doesn't need semt, just don't copy it into runtime.inc.

    • [ARM] Rewire -mfpu=fp-armv8 as VFPv5 + D32 + DP · c8d61ab8 
      fp-armv8 is currently defined as a double precision FPv5 with 32 D
registers *and* a special FP_ARMv8 bit. However FP for ARMv8 should only
bring 32 D registers on top of FPv5-D16 so this FP_ARMv8 bit is
spurious. As a consequence, many instruction patterns which are guarded
by TARGET_FPU_ARMV8 are unavailable to FPv5-D16 and FPv5-SP-D16.

This commit gets rid of TARGET_FPU_ARMV8 and rewire all uses to
expressions based on TARGET_VFP5, TARGET_VFPD32 and TARGET_VFP_DOUBLE.
It also redefine ISA_FP_ARMv8 to include the D32 capability to
distinguish it from FPv5-D16. At last, it sets the +fp.sp for ARMv8-R to
enable FPv5-SP-D16 (ie FP for ARMv8 with single precision only and 16 D
registers).
