nir/search: Use the correct bit size for integer comparisons

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

It seems like maybe this should return a different type based on Gen.  Q

previous Gens can generate 64-bit moves.

i965: Really don't emit Q or UQ moves on Gen < 8

It's much easier to do this in the generator rather than while coming
out of NIR.  brw_type_for_nir_type doesn't know the Gen, so we'd have to
add a bunch of plumbing.  The alternate fix is to not emit int64 moves
for doubles in the first place... but that seems even more difficult.

This change won't catch non-MOV instructions that try to use 64-bit
integer types on Gen < 8.  This may convert certain kinds of bugs in to
different kinds of bugs that are more difficult to detect (since the
assertions in the function won't catch them).

NOTE: I don't think anything can emit mixed-type 64-bit moves until the
same platform supports both ARB_gpu_shader_fp64 and
ARB_gpu_shader_int64.  When we enable int64 on Gen < 8, we can solve
this problem other ways.

This prevents regressions on HSW in the next patch.

Previously both sources were unsized.  This caused problems when the
