Previously, we might not have required all coordinates to be in WQM if
there were other args before them. We should probably also require that
the offset is in WQM.

Fixes several dEQP-VK.robustness.robustness2.* tests on GFX8. Generations
other than GFX8 don't fail the tests because bounds-checking is done using
the index (making it per-vertex).

From comment in emit_mimg():
We don't need the bias, sample index, compare value or offset to be
computed in WQM but if the p_create_vector copies the coordinates, then it
needs to be in WQM.

Compute the number of components of the destination vector from the
bitsize when eg. a 16-bit vec2 vertex fetches is splitted. This is
because the dst will be a v1, so the p_create_vector should be created
from two v2b fro both sizes to match.
This prevents a regression from the next change which will split
typed vertex buffer loads on GFX6 and GFX10+.

avoids errors seen when building on OpenBSD/amd64
../src/amd/compiler/aco_instruction_selection.cpp:1677:62: error: ambiguous conversion for functional-style cast from 'unsigned long' to 'aco::Operand'
bld.vop3(aco_opcode::v_mul_f64, Definition(dst), Operand(0x3FF0000000000000lu), tmp);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
glibc uses unsigned long for uint64_t on LP64 archs and unsigned long long for
uint64_t on ILP32 archs. On OpenBSD unsigned long long is used for uint64_t
on all archs.
The Operand constructors are uint8_t uint16_t uint32_t uint64_t
use UINT64_C so lu or llu suffix will be used as needed.

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.
