b4383821e7 aco: don't modify exec in p_interp_gfx11 
The RDNA3 ISA docs say that lds_param_load write the entire quad
regardless of exec, so this isn't needed.

dae1629778 aco: disable sdwa on gfx11 
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.

We can copy any value into a 16-bit subregister with a 3 dword
v_pack_b32_f16 on GFX10 or a v_and_b32+v_or_b32 on GFX9.

Because the generated code can depend on the register assignment and to
improve constant propagation, Builder::copy creates a p_create_vector in
the case of sub-dword literals.

d169f09e37 aco: be more careful combining additions that could wrap into loads/stores 
SMEM does the addition with 64-bits, not 32. So if the original code
relied on wrapping around (for example, for subtraction), it would break.

Apparently swizzled MUBUF accesses also have issues with combining
additions that could overflow. Normal MUBUF accesses seem fine.
