The previous code always compared integers as 64-bit. Due to variations
in sign-extension in the code generated by nir_opt_algebraic.py, this
meant that nir_search doesn't always do what you want. Instead, 32-bit
values should be matched as 32-bit and 64-bit values should be matched
as 64-bit. While we're here we unify the unsigned and signed paths.
Now that we're using the right bit size, they should be the same since
the only difference we had before was sign extension.
This gets the UE4 bitfield_extract optimization working again. It had
stopped working due to the constant 0xff00ff00 getting sign-extended
when it shouldn't have.

Previously both sources were unsized. This caused problems when the
thing being shifted was 64-bit but the shift count was 32-bit. The
expectation in NIR is that all unsized sources (and destination) will
ultimately have the same size.
The changes in nir_opt_algebraic.py are to prevent errors like:

This change makes me wonder whether double packing should be
