tree-optimization/105312 - fix ISEL VCOND expansion
The following aligns ISEL VEC_COND_EXPR expansion using VCOND
with the optab query done by vector lowering. Instead of only
allowing the signed optab to provide EQ/NE compares we allow both
here though since there seems to be no documented canonicalization.
