[AArch64] Rename cmp_result iterator
The comparison results provided by the V_cmp_result/v_cmp_result
attribute were simply the corresponding integer vector. We'd also
like to have easy access to the integer vector for SVE, but using
"cmp_result" would be confusing because SVE comparisons return
predicates instead of vectors. This patch therefore renames the
attributes to the more general V_INT_EQUIV/v_int_equiv instead.
As to the capitalisation: there are already many iterators that use
all lowercase vs. all uppercase names to distinguish all lowercase
vs. all uppercase expansions (e.g. fcvt_target and FCVT_TARGET).
It's also the convention used for the built-in mode/MODE/code/CODE/etc.
attributes. IMO those names are easier to read at a glance, rather than
relying on a single letter's difference.
