With the new handling of bool types, the conversion to float in glsl_to_nir
should not apply to bool types anymore.

All alu instructions emitted with native_integers=false expect float
(or bool in some cases) constants, so this change is necessary.
This will cause changes with some intrinsics which had integer sources,
such as nir_intrinsic_load_uniform. Apparently it might cause issues with
some opt passes, but perhaps those don't apply in OpenGL ES 2.0 cases?

GL_ARB_gl_spirv does not provide a sampler deref for e.g. texelFetch(),
so we can't assume that both are present and identical. Simply lower
each if it is present.
Fixes regressions in GL_ARB_gl_spirv tests since I switched everyone to
using this pass. Thanks to Alejandro Piñeiro for catching these.

In all GLSL ES versions output variables in fragment shader are allowed
to be invariant.
From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 1.00 spec:
"Only the following variables may be declared as invariant:
...
- Built-in special variables output from the fragment shader."
From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 3.00 spec:
"Only variables output from a shader can be candidates for invariance."

you & them with 0x7. Fortunately, we have plenty of bits.

NIR metadata validation verifies that the debug bit was unset (by a call
to nir_metadata_preserve) if a NIR optimization pass made progress on
the shader. With the expectation that the NIR shader consists of only a
single main function, it has been safe to call nir_metadata_preserve()
iff progress was made.
However, most optimization passes calculate progress per-function and
then return the union of those calculations. In the case that an
optimization pass makes progress only on a subset of the functions in
the shader metadata validation will detect the debug bit is still set on
any unchanged functions resulting in a failed assertion.
This patch offers a quick solution (short of a larger scale refactoring
which I do not wish to undertake as part of this series) that simply
unsets the debug bit on unchanged functions.
