ir3/nir: Add new NIR AlgebraicPass for lowering imul
Currently, ir3 backend compiler is lowering integer multiplication from:
dst = a * b
to:
dst = (al * bl) + (ah * bl << 16) + (al * bh << 16)
by emitting this code:
mull.u tmp0, a, b ; mul low, i.e. al * bl
madsh.m16 tmp1, a, b, tmp0 ; mul-add shift high mix, i.e. ah * bl << 16
madsh.m16 dst, b, a, tmp1 ; i.e. al * bh << 16
which at that point has very low chances of being optimized.
This patch adds a new nir_algebraic.AlgebraicPass to performs this
lowering during NIR algebraic optimization passes, giving it a better
chance for optimizing the resulting code.

freedreno/ir3: Add new ir3 pass to fold out fp16 conversions
This pass tries to fold f2f16 conversion into alu instructions.
This will be useful to help reduce the number of instructions once
mesa starts supporting precision lowering. For example:
add.f r0.w, r0.w, c0.x
cov.f32f16 hr2.x, r0.w
to
add.f hr2.x, r0.w, c0.x
Additionally this pass also tries to fold f2f16 conversion into load_input
instruction:
bary.f r0.x, 3, r0.w
cov.f32f16 hr0.x, r0.x
to
bary.f hr1.x, 3, r0.x
v2: Edit to not fold OPC_MAX_F and OPC_MIN_F, since that's not valid.
v3: Add OPC_ABSNEG_F to the blacklist as well.
v4: Don't remove dead cov instructions, DCE will do that later; don't
iterate through sources when a cov only has one; remove special
handling of IR3_REG_ARRAY and IR3_REG_RELATIV.
v5: Handle folding into u32.u32 movs of floats correctly, don't bail
out on IR3_REG_RELATIV or IR3_REG_ARRAY movs.
