aarch64: Add arch support for LSE128 extension
Enable the `+lse128' feature modifier which, together with new
internal feature flags, enables LSE128 instructions, which are
represented via the new `_LSE128_INSN' macro.
gas/ChangeLog:
* config/tc-aarch64.c (aarch64_features): Add new "lse128"
entry.
include/ChangeLog:
* include/opcode/aarch64.h (enum aarch64_feature_bit): New
AARCH64_FEATURE_LSE128 feature bit.
(enum aarch64_insn_class): New lse128_atomic instruction class.
opcodes/ChangeLog:
* opcodes/aarch64-tbl.h (aarch64_feature_lse128): New.
