This commit introduces a new way to zero-init variables but keep the
old one to not break any existing behavior.
With this change GLSLZeroInit becomes an integer, with the following
possible values:
- 0: no 0 init
- 1: current behavior
- 2: new behavior. Similar to 1, except ir_var_function_out type are
0 initialized but ir_var_shader_out.
The rationale behind 2 is: zero initializing ir_var_shader_out can
prevent some optimization where out variables are completely eliminated
when not written to.
On the other hand, zero initializing "ir_var_function_out" has no
effect on correct shaders but typically helps shadertoy since the main
function is:
void mainImage(out vec4 fragColor) { ... }
So with this change we're sure that fragColor will always get a value.

Shared globals and glsl_zero_init can cause linker errors if the
variable is only initialized in 1 place.
This commit adds a flag to variables that have been implicitely
initialized to be able in this situation to keep the explicit
initialization value.
Without this change the global-single-initializer-2-shaders piglit
test fails when using glsl_zero_init.

This commit makes zero_init a bitfield of types of variables to zeroinit.
This will allow some flexibility that will be used in the next commit.

The Vulkan spec says:
"shaderInt16 specifies whether 16-bit integers (signed and unsigned)
are supported in shader code. If this feature is not enabled, 16-bit
integer types must not be used in shader code."
I think it's just safe to enable it because 16-bit integers should
be fully supported with LLVM and also with ACO and GFX8+. On GFX8
and earlier generations, throughput of 16-bit int is same as 32-bit
but that should't change anything.
For GFX6-GFX7 ACO support, we have to implement conversions without
SDWA.

Instead of open-coding uniform -> UBO lowering, let's instead use the
one that already exists. This should make things a bit simpler going
forward.

Zink needs to know the sizes of UBOs, and for normal UBOs we get this
from the nir_var_mem_ubo variables. This allows us to treat all of these
the same way.
We're about to need the same information for the in-progress D3D12
driver, so let's do this in a central location instead of in the driver.
This version is also a bit more careful than the Zink version. In
particular, for two reasons:
1. We increase the variable bindings when we adjust the pre-existing
UBOs.
2. We increase shader->info.num_ubos when we insert a new UBO variable.

It's not great to use shader_info for this information, because it
might have gone through lowering of uniforms to UBOs, which can change
the number of UBOs. So let's make sure we know the size of the
UniformBlocks array from when the shader was linked instead.

There is no uint to int implicit conversion in glsl, this is just
a typo in the name of this function. The correct one would be:
has_implicit_int_to_uint_conversion.

Some applications incorrectly use GL_LINEAR* values for integers texture.
copyimage.c already implemented a tolerance for such app in prepare_target_err.
This commit adds a boolean that will treat GL_LINEAR* filters as
GL_NEAREST for integer textures.

These come from the disasm tests, and fix our disasm of blob's
