radv: Implement VK_AMD_shader_info

we retrieve cached shaders.

intel/compiler/gen9: Pixel shader header only workaround

Fixes intermittent GPU hangs on Broxton with an Intel internal
test case.

There are plenty of similar fragment shaders in piglit that do
not use any varyings and any uniforms. According to the
documentation special timing is needed between pipeline stages.
Apparently we just don't hit that with piglit. Even with the
failing test case one doesn't always get the hang.

Moreover, according to the error states the hang happens
significantly later than the execution of the problematic shader.
There are multiple render cycles (primitive submissions) in between.
I've also seen error states where the ACTHD points outside the
batch. Almost as if the hardware writes somewhere that gets used
later on. That would also explain why piglit doesn't suffer from
this - most tests kick off one render cycle and any corruption
is left unseen.

v2 (Ken): Instead of enabling push constants, enable one of the
          inputs (PSIZ).
v3 (Ken, Jason): Use LAYER instead making vulkan emit_3dstate_sbe()

glsl/linker: generalize validate_explicit_variable_location for SSO

For non-SSO programs, we only need to validate outputs, since
the cross validation of outputs to inputs will ensure that we
produce linker errors for invalid inputs too.

Hoever, for the SSO path there is no output to input validation,
so we need to validate inputs explicitly. Generalize the function
so it can handle this as well.

Also, notice that vertex shader inputs and fragment shader outputs
are already validated in assign_attribute_or_color_locations()
for both SSO and non-SSO paths, so we should not try to validate
that here again (in fact, the function would require explicit
paths to handle these two cases properly).

glsl/linker: fix location aliasing checks for interface variables

The existing code was checking the whole interface variable rather
than its members, which is not what we want: we want to check
aliasing for each member in the interface variable.

Surprisingly, there are piglit tests that verify this and were
passing due to a bug in the existing code: when we were computing
the last component used by an interface variable we would use
the 'vector' path and multiply by vector_elements, which is 0 for
interface variables. This made the loop that checks for aliasing
be a no-op and not add the interface variable to the list of outputs
so then we would fail to link when we did not see a matching output
for the same input in the next stage. Since the tests expect a
linker error to happen, they would pass, but not for the right
reason.

Unfortunately, the current implementation uses ir_variable instances
to keep track of explicit locations. Since we don't have
ir_variables instances for individual interface members, we need
to have a custom struct with the data we need. This struct has
the ir_variable (which for interface members is the whole
interface variable), plus the data that we need to validate for
each aliased location, for now only the base type, which for
interface members we will take from the appropriate field inside
the interface variable.

Later patches will expand this custom struct so we can also check
other requirements for location aliasing, specifically that
we have matching interpolation and auxiliary storage, that once
again, we will take from the appropriate field members for the
interface variables.

This is perfectly valid but when lower_simd_width comes along, it simply
splits into two instructions which both have conditional modifiers.
This is a problem since we're reading the flag register.  This commit
