ede0630f9e aco: use v_fma_mix_f32 for v_fma_f32 with 2 fp16 representable, different literals 
We can pack two fp16 literals into one 32bit literal and use opsel to select
the correct value. Note that LLVM currently disassembles these instructions
incorrectly.

2c40215ab9 aco/optimizer: Change v_cmp with subgroup invocation to constant. 
When a shader has a comparison with the subgroup invocation id,
we can use a constant instead, saving a VALU instruction.
When the constant can't be represented as a 64-bit literal,
use the s_bfm_b64 instruction to generate it instead, which
is still a win.

faba30a8f3 aco/optimizer: Optimize p_extract + v_mul_u32_u24 to v_mad_u32_u16. 
This should perform the same but removes SDWA from the address
calculations in NGG culling shaders for example.

This is done because SDWA is no longer available on GFX11.

c8445c1691 aco: Change inverse-comparison optimization to work with s_not 
Some time ago we stopped using s_andn2 with exec for boolean NOT.
The reasoning behind that change was that those booleans will be
always ANDed with exec when necessary.

This inhibited the inverse-comparison optimization in most cases
which is fixed by this patch.
