It isn't safe to modify the exec mask before the discard block, and the
definition interferes with GFX11 NOP insertion.
Just use s[0:1] instead, since we won't be using it.

If the fragment shader exports MRTZ and the epilog some color exports,

If we're applying the literal 0x3f800000 to a fp16 vop3p instruction, we
shouldn't use the 1.0 inline constant, because the hardware will use the
16-bit 1.0: 0x00003c00.

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.

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.

This migration was done with libclang-based automatic tooling, which
performed these replacements:
* Operand(uint8_t) -> Operand::c8
* Operand(uint16_t) -> Operand::c16
* Operand(uint32_t, false) -> Operand::c32
* Operand(uint32_t, bool) -> Operand::c32_or_c64
* Operand(uint64_t) -> Operand::c64
* Operand(0) -> Operand::zero(num_bytes)
Casts that were previously used for constructor selection have automatically
been removed (e.g. Operand((uint16_t)1) -> Operand::c16(1)).

When the offset is negative, reg() isn't 255. Fix this by splitting
SGPR and literal emission. While we are at it, adjust a comment
saying that literals are also accepted on GFX6 which is wrong.
