My first attempt to fix it ended up stomping classes to zero because it
happened too eary. Now it happens after we have the whole method parsed
but before we go searching for strings.

The previous implementation was using temporal clamping variable within geometry shader.
It caused the framebuffer_layer_id input to be ignored, so gl_Layer would end up with a value of 0.
The fix removes the use of the temp variable.
Tested using CTS 4.6.6.0 test cases:
./glcts --deqp-case=dEQP-GL45-ES31.functional.geometry_shading.layered.fragment_layer_cubemap
./glcts --deqp-case=dEQP-GL45-ES31.functional.geometry_shading.layered.fragment_layer_3d
./glcts --deqp-case=dEQP-GL45-ES31.functional.geometry_shading.layered.fragment_layer_2d_array
./glcts --deqp-case=dEQP-GL45-ES31.functional.geometry_shading.layered.fragment_layer_2d_multisample_array
These tests fail before and pass after the change.

ir3_ra allocates registers in a round-robin fashion to avoid false
dependencies. In order to do this, it keeps track of a "file start"
register for each register file and will search starting from there for
available registers.
This file start is initialized at the beginning of RA of kept across
blocks, including across the preamble. This means that a change that
only affects the preamble may cause changes in how registers are
allocated in the main shader. This may result in more or less copies,
and more or less false dependencies which changes the behavior of
postsched.
Changes in the preamble affecting the main shader makes it more
difficult to analyze shader-db results, as I often find myself chasing
down a regression that is just caused by RA/postsched "bad luck" in a
main shader that didn't actually change. Prevent this by resetting the
file start at the beginning of the main shader.

The vulkan spec says that we should ignore memoryOffset when
VkBindImageMemorySwapchainInfoKHR is present. wsi common assumes that we
bind the wsi image at offset 0, so set the offset to 0. This change
aligns with common wsi, and also obeys dedicated alloc requirement.

When spilling registers on Valhall we are careful to leave the TLS
pointer aligned on 16 byte boundaries (so as to avoid accesses
crossing those boundaries). However, within the spill code we don't
need to have 16 byte alignment for spills of 32 or 64 bit values.
In the common case where most spills are 32 bits, we can save nearly
75% of the memory used by just aligning to 32 bit boundaries.

On v11+, all small integers instruction variants are gone, however we
can now use widen on src0 just fine.
That mean we can get ride of mid conversion by relying on swizzle
instead while respecting signess of the inner instruction.
This helps a little bit on clpeak with panvk+clvk, shader-db is also
happy:
