f03c20ffae aco: fix WQM for texture instructions with args before the coordinates
Previously, we might not have required all coordinates to be in WQM if
there were other args before them. We should probably also require that
the offset is in WQM.

824eba2148 aco: don't consider a phi trivial if same's register doesn't match the def
For example:
 s2: %688:s[32-33] = p_linear_phi %3:s[10-11], %688:s[32-33]
would have been considered trivial.

This might happen due to parallelcopies when assigning phi registers.

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

689ce1f39d aco/ra: Remove always-false conditions
All code paths that set "found" to true either break or return before the
loop header is reached again, so the checks are unnecessary.

9bbd6162a9 aco/ra: Introduce PhysRegInterval helper class
This mainly clarifies the semantics of register bounds (inclusive vs
exclusive), and further groups related varaibles together to clarify
sliding-window-style loops.

67c1f32228 aco/ra: Update register use bounds before recursing in get_regs_for_copies
Delaying the call to adjust_max_used_regs until after get_regs_for_copies
returns puts the RA context into a state where registers past max_used_gpr
may be blocked. This isn't an issue on its own, but it adds a surprising
corner case to get_reg_simple that is easily avoided now.
