pass was probably broken on GFX11 because of this.

As monotonic_buffer_resource is not thread-safe,
we use a thread_local instance which gets allocated once.
This change reduces the compile time spent in ACO by
approximately 10%.

Instead of SDWA v_mov_b32/v_xor_b32, we can use a combination of
v_add_u16/v_sub_u16 (add/sub swap, similar to xor swap) and v_perm_b32
with a literal.
I don't know yet if GFX11 adds any new instructions which makes this
easier, but this approach should have full functionality.

This should be kept to only things aco uses, and expanded when
radeonsi support is added. Things should be removed if lowered in NIR.

Instead, we can rely on the fact that subdword definitions
must preserve the unused bits while dword definitions either
pad or sign-extend.

This commit introduces a new struct SubdwordSel
in order to ease and clean up the usage of SDWA
selections. This includes removing the distinction
between register-allocated and fixed SDWA selections.
Instead, SDWA selections can now also access the high
bits of subdword variables. Alignment and sizes are
validated accordingly. Size, offset and sign_extend
can be evaluated via helper methods.

but with different descriptors. Since they will be loading from the same
