nir/search: Introduce a src_is_type() helper for 'a@type' handling.

Currently, 'a@type' can only match if 'a' is produced by an ALU
instruction.  This is rather limited - there are other cases we
can easily detect which we should handle.

Extending the code in-place would be fairly messy, so we introduce
a new src_is_type() helper.
