e5899c1e88 nir: rename nir_op_fne to nir_op_fneu
It was always fneu but naming it fne causes confusion from time to time. So
lets rename it. Later we also want to add other unordered and fne, this is
a smaller preparation for that.

ce4064fe2f nir/ lower_int_to_float: Handle umax and umin
8e1b75b3 introduced umax/umin in order to lower iand/ior for (n)eq zero.
That breaks the lower_int_to_float pass, because umax and umin weren't
handled there.

Tested with lima. The other users of nir_lower_int_to_float
(etnaviv, freedreno) should also have that issue.

f387c2b238 nir: remove bool lowering from lower_int_to_float
Removes the bool_to_float logic from the int_to_float pass, so that both
can be used separately. By having separate passes we have better validation
and it makes it possible to use with the lower_ftrunc option (int lowering
generates ftrunc, but lower_ftrunc generates bools, ftrunc lowering should
probably be reworked). For now we always expect lower_bool to come after
lower_int.

Also fixes f2i32 to become ftrunc and adds u2f/f2u cases.

e584fd894e nir: silence three compiler warnings seen with MinGW
Silence two unused var warnings.  And init elem_size, elem_align to
zero to silence "maybe uninitialized" warnings.

f2dc0f2872 nir: Drop imov/fmov in favor of one mov instruction
The difference between imov and fmov has been a constant source of
confusion in NIR for years.  No one really knows why we have two or when
to use one vs. the other.  The real reason is that they do different
things in the presence of source and destination modifiers.  However,
without modifiers (which many back-ends don't have), they are identical.
Now that we've reworked nir_lower_to_source_mods to leave one abs/neg
instruction in place rather than replacing them with imov or fmov
instructions, we don't need two different instructions at all anymore.

443c5a3cd6 nir: add int_to_float lowering pass
This new pass lowers ints and bools to floats. It allows hardware
that doesn't have native integers (e.g. Mali4x0) use the same
code paths as modern hardware.

It uses newly introduced pass to gather SSA types and should be
used as late as possible.
