96fafcca63 aco: propagate temporaries into PSEUDO instructions if it can take it 
This patch relaxes copy-propagation for PSEUDO instructions with
subdword Operands / Definitions:
general:
- only propagate VGPR temps if the Definition is VGPR (or on p_as_uniform)

parallelcopy/create_vector/phis:
- size has to be the same

extract_vector/split_vector:
- propagate SGPR temps on GFX9+ or if the Definitions are not subdword
- split_vector: size must not increase

bbdafd6ab3 aco: optimize v_mad_u32_u16 with acc=0 to v_mul_u32_u24 
v_mad_u32_u16 will be selected by isel to keep the range analysis
information around and to combine more v_add_u32+v_mad_u32_u16
together. When it's not possible to optimize that pattern, fallback
to v_mul_u32_u24 which is VOP2 instead of VOP3.

No fossils-db changes.
