aarch64: Prevent generation of /M BRKAS and BRKBS
Bit of a brown-paper-bag bug, but: GCC was generating
non-existent merging forms of BRKAS and BRKBS. Those
instructions only support zero predication (although
BRKA and BRKB support both).
gcc/
* config/aarch64/aarch64-sve.md (*aarch64_brk<brk_op>_cc): Remove
merging alternative.
(*aarch64_brk<brk_op>_ptest): Likewise.
gcc/testsuite/
* gcc.target/aarch64/sve/acle/general/brka_1.c: Expect a separate
PTEST instruction.
* gcc.target/aarch64/sve/acle/general/brkb_1.c: Likewise.
