This patch splits out FCMA as a feature from Armv8.3-A and adds it as a separate
feature bit which now controls 'TARGET_COMPLEX'.
gcc/ChangeLog:
* config/aarch64/aarch64-arches.def (FCMA): New feature bit, can not be
used as an extension in the command-line.
* config/aarch64/aarch64.h (TARGET_COMPLEX): Use FCMA feature bit
rather than ARMV8_3.
