23d5865f42 aco: refactor nir_op_imul selection
Previously, the optimization to use v_mul_lo_u16 for
32bit multiplications was done in instruction_selection.
This was moved to the optimizer to ease some case distinctions.

The mixed results are due to increased use of SDWA.

66e51dc474 aco: Remove use of deprecated Operand constructors
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)).

8e961b91c3 aco: optimize v_add+v_lshlrev to v_mad_u32_u24 on GFX6-8
This optimizes v_add(c, v_lshlrev(a, b)) to v_mad_u32_u24(b, 1<<a, c)
if 'a' is a constant (less than or equal to 6 to avoid creating
literals) and 'b' known to be a 16-bit or a 24-bit value.

On GFX9+, this is already optimized to v_lshl_add_u32.

No fossils-db changes.
