Our previous handling of barriers always used the big hammer and didn't
correctly emit memory barriers when specified along with a control
barrier. This commit completely reworks the way we emit barriers to
make things both more precise and more correct.

The introduction of 16-bit types with VK_KHR_16bit_storages implies that
push constant offsets could be multiple of 2-bytes. Some assertions are
updated so offsets should be just multiple of size of the base type but
in some cases we can not assume it as doubles aren't aligned to 8 bytes
in some cases.
For 16-bit types, the push constant offset takes into account the
internal offset in the 32-bit uniform bucket adding 2-bytes when we access
not 32-bit aligned elements. In all 32-bit aligned cases it just becomes 0.

Range in 16-bit push constants load was being calculated

The SPIR-V parser splits in/out struct variables and creates
a separate variable for each first-level member of the struct.
When the struct variable has an initializer this means that we also
need to split the initializer.

Technically, the GLSLang bug related to this can also affect SSBO writes
where the bool -> uint conversion is missing. However, the only known
shipping application with an old enough version of GLSLang to cause
issues with this is the new DOOM game so we keep the workaround as small
as possible.

Previously, we were storing a pointer to the vtn_value because we use it
to look up decorations when we create input/output variables. This
works, but it also may be useful to have the id itself so we may as well
store that instead.

Now that higher levels are enforcing decoration sanity, we don't need
the vtn_asserts here. This function *should* be safe but we still want
a few well-placed regular asserts in case something goes awry.

This reworks the error checking on our generic handling of decorations.
The objective is to validate all of the SPIR-V assumptions we make
up-front and convert redundant checks to compiled-out asserts. The most
important part of this is to ensure that member decorations only occur
on OpTypeStruct and that the member is never out-of-bounds. This way
later code can assume that the member is sane and not have to worry
about OOB array access due to a misplaced OpMemberDecorate.

This is a bit simpler since we have fewer enum values in the case. It's
also a bit more efficient because we're making fewer glsl_get_* calls.
While we're at it, add better type validation.

When walking over all the cases in a OpSwitch, take in account the bitsize

The Talos Principle contains shaders with an OpSelect between two
vectors where the condition is a scalar boolean. This is technically
against the spec bout nir_builder gracefully handles it by splatting
out the condition to all the channels. So long as the condition is a
boolean, just emit a warning instead of failing.

Pointers with no storage type are converted to inout variables but SSA
values and pointers with a storage type (which turns into a uint or
uvec2) are just input variables.
Previously, we just gave them exactly the same type as the respective
image (which already had a sampler2D or similar type). Now they have
their own base type and a pointer to the vtn_type for the image.
