There is no good reason why we should have the same logic repeated in
get_vulkan_resource_index and vtn_ssa_offset_pointer_dereference. If
we're a bit more careful about how we do things, we can just use the one
function and get rid of the other entirely. This also makes the push
constant special case a lot more clear.

These helpers are much nicer than just using assert because they don't
kill your process. Instead, it longjmps back to spirv_to_nir(), cleans
up all the temporary memory, and nicely returns NULL. While crashing is
completely OK in the Vulkan world, it's not considered to be quite so
nice in GL. This should help us to make SPIR-V parsing much more
robust. The one downside here is that vtn_assert is not compiled out in
release builds like assert() is so it isn't free.

This commit reworks the way that logging works in SPIR-V to provide
richer and more detailed logging infrastructure. This commit contains
several improvements over the old mechanism:
1) Log messages are now more detailed. They contain the SPIR-V byte
offset as well as source language information from OpSource and
OpLine.
2) There is now a logging callback mechanism so that errors can get
propagated to the client through debug callbak extensions.

Gather operations in both GLSL and SPIR-V require a sampler. Fixes

We should use the result type of the OpSampledImage opcode, rather than
the type of the underlying image/samplers.
This resolves an issue when using separate images and shadow samplers
with glslang. Example:
layout (...) uniform samplerShadow s0;
layout (...) uniform texture2D res0;
...
float result = textureLod(sampler2DShadow(res0, s0), uv, 0);
For this, for the combined OpSampledImage, the type of the base image
was being used (which does not have the Depth flag set, whereas the
result type does), therefore it was not being recognised as a shadow
sampler. This led to the wrong LLVM intrinsics being emitted by RADV.

Per the SPIR-V spec 2.11 Structured Control Flow:
"The only blocks in a construct that can branch outside the construct are
...
- a break block for the innermost loop it is inside of.
..."
With
"Break block: A block containing a branch to the Merge Block of a loop header's merge instruction."
Note that it puts no restriction on not being in an if or switch within the innermost loop.
This passes the loop_break block to the switch body so it can properly detect loop breaks.
