This optimization doesn't work for SDWA or DPP multiplications and we
can't do it if denormal flushing is required because v_cndmask_b32 doesn't
do that and we can't do it if we can't assume operands are finite because
0.0 * inf is NaN, not 0.

Only try to invalidate L2 if we actually hit one of the incoherent images.
Note we may actually insert some extra flushes at the end of a command
buffer so that we may asume the caches are clean the start of the next
command buffer. However, on average I think that case is uncommon
enough that being able to make assumptions at the start of a cmdbuffer
is beneficial. Especially since MSAA is somewhat rare in more recent
games.

Way faster than the previous one, especially with a large number of

This doesn't have much of an effect right now, but the previous allocator

In the following cases:
- lower 16 bits are extracted and the shift amount is 16 or more
- lower 8 bits are extracted and the shift amount is 24 or more
the undesireable upper bits are already shifted out, and therefore
there is no need to add SDWA to the v_lshlrev instruction.

When the determinant that we use for calculating triangle area
is NaN, it's not possible to decide the facing of the triangle.
This can happen when a coordinate of one of the triangle's vertices
is INFINITY. It's better to just accept these triangles in the shader
and let the PA deal with them.
Let's do the same for +/- Infinity too.
Though we haven't seen this yet, it may be troublesome as well.
