aarch64: Force TImode values into even registers
The LSE CASP instruction requires values to be placed in even
register pairs. A solution involving two additional register
classes was rejected in favor of the much simpler solution of
simply requiring all TImode values to be aligned.
* config/aarch64/aarch64.c (aarch64_hard_regno_mode_ok): Force
16-byte modes held in GP registers to use an even regno.
