[AArch64][SVE 06/32] Generalise parse_neon_reg_list
Rename parse_neon_reg_list to parse_vector_reg_list and take
in the required register type as an argument. Later patches
will reuse the function for SVE registers.
gas/
* config/tc-aarch64.c (parse_neon_reg_list): Rename to...
(parse_vector_reg_list): ...this and take a register type
as input.
(parse_operands): Update accordingly.
