[AArch64][SVE 22/32] Add qualifiers for merging and zeroing predication

This patch adds qualifiers to represent /z and /m suffixes on
predicate registers.

include/
* opcode/aarch64.h (AARCH64_OPND_QLF_P_Z): New aarch64_opnd_qualifier.
(AARCH64_OPND_QLF_P_M): Likewise.

opcodes/
* aarch64-opc.c (aarch64_opnd_qualifiers): Add entries for
AARCH64_OPND_QLF_P_[ZM].
(aarch64_print_operand): Print /z and /m where appropriate.

gas/
* config/tc-aarch64.c (vector_el_type): Add NT_zero and NT_merge.
(parse_vector_type_for_operand): Assert that the skipped character
is a '.'.
(parse_predication_for_operand): New function.
(parse_typed_reg): Parse /z and /m suffixes for predicate registers.
(vectype_to_qualifier): Handle NT_zero and NT_merge.
