[AArch64] Handle 64bit vector s/umull from extracts
This is similar to D153632, but for mul nodes instead of add/sub. They get
recognised in LowerMUL in order to detect the mul(ext, ext), in a way that will
work for i64 nodes as well as i16/i32. This extends it to look for
mul(subvector_extract(ext(x), 0), subvector_extract(ext(y), 0)), generating a
subvector_extract(mull(x,y)) if it matches.
