aco: Add preload_preserved pseudo instruction
...
These are helper instructions for the spill_preserved pass to insert
reloads for registers that are preserved by the ABI, yet
clobbered by the callee shader.
There is one p_reload_preserved instruction at the end of each block.
This allows us to insert reloads early, to alleviate the high latency of
scratch reloads.

...
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
We don't have v_permlane64_b32 yet, but we can still optimize it using
shared vgprs. Using the DPP16 row mask, we can even avoid writing exec.
With v0 input/output and v24/v25 as shared vgprs, this results in:
v_mov_b32_dpp v24, v0 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf
v_mov_b32_dpp v25, v0 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf
v_mov_b32_dpp v0, v24 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf
v_mov_b32_dpp v0, v25 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf

Sadly amd only made this behavior controlable with global state.
We add a new pseudo opcode for this purpose and change FP16_OVFL
for each instruction. Ideally we would only do it once for clauses
and after ilp scheduling, but this can be improved in the future.
