If there are no leaves, the root node bounds still span -inf/inf.
Making empty BLASs infinite-sized guarantees ray traversal needs to
enter the BLAS (and immediately exit because it's empty). Remove the
BLAS from the BVH entirely by marking its bounds as NaN. As a bonus,
this works around RADV encountering issues in Silent Hill 2 on RDNA4 due
to infinite-sized BVHs.

This reduces duplication: we only need to distinguish between Windows
and Unix in one place.
The previous code was inconsistent about using either the `platforms`
option, or the `host_machine`. Following the logic described in
commit 94379377 "lavapipe: build "Windows" check should use the host machine, not the `platforms` option.",
I've assumed that checking the host machine is the more-correct version
and used that.

This consistently uses `NAME.dll` on Windows, `libNAME.dylib` on Darwin
derivatives such as macOS, and `libNAME.so` on Linux, *BSD and so on.
It's also consistent about using the local variable name `icd_file_name`
for this name in every Vulkan driver, which was already the case in many
but not all drivers.
Some of these drivers probably don't make sense (or don't work) on
Windows and/or macOS, but if this is kept consistent for all drivers,
it should avoid the need for driver-specific commits like
commit 611e9f29e "lavapipe: fix icd generation for windows",
commit 951f3287 "lavapipe: set empty dll prefix",
commit 13e7a39f "lavapipe: fixes for macOS support",
commit 7008e655 "radv: Update JSON generator if Windows" and so on,
each time a driver is found to be relevant on more platforms than
previously believed.

Because s_sendmsg dealloc_vgprs waits for every counter except vs_count,
and the message bus has limited throughput, we should only insert the dealloc
when we know that it's beneficial.

Usually wave64 performs better for fragment shaders,
because LDS sharing for interpolation is better.
But the rt traversal loop divergence is likely high enough to make
wave32 better on GFX10.

If the application really thinks it needs pswave32, let it use it.
Fragment shaders also have no concept of full subgroups, so the existing
code that chooses the subgroup size will work already.
For pre raster stages, we cannot allow this because of potential mismatches
in merged stages.

SMEM instructions mask off the low bits for the base and offset sources
both before and after they're added. However, NIR expects ACO to only
