526a8de22d nir/spirv: Make a decoration switch complete
Getting rid of the default case makes the compiler warn if we are missing
cases.  While we're here, we also add the one missing case.

62c6e94bd6 nir/spirv: Make unhandled decorations and capabilities non-fatal

5a1e56f344 nir/spirv: Complete the list of capabilities
Previously we supported a subset of capabilities and just left a default
case for the others.  It's time to stop being lazy and actually audit the
capabilities.  This should bring them up-to-date with reality.

dfbae7d64f nir/algebraic: support for power-of-two optimizations
Some optimizations, like converting integer multiply/divide into left/
right shifts, have additional constraints on the search expression.
Like requiring that a variable is a constant power of two.  Support
these cases by allowing a fxn name to be appended to the search var
expression (ie. "a#32(is_power_of_two)").

The test now fails at a tes evaluation shader with unsized output arrays.

The ARB_enhanced_layouts spec says:

   "It is a compile-time error to apply xfb_offset to the declaration of an

5b2675093e glsl: handle implicit sized arrays in ssbo
The current code disallows unsized arrays except at the end of
an SSBO but it is a bit overzealous in doing so.

struct a {
	int b[];
	int f[4];
};

is valid as long as b is implicitly sized within the shader,
i.e. it is accessed only by integer indices.

I've submitted some piglit tests to test for this.

This also has no regressions on piglit on my Haswell.
This fixes:
GL45-CTS.shader_storage_buffer_object.basic-syntax
GL45-CTS.shader_storage_buffer_object.basic-syntaxSSO

This patch moves a chunk of the linker code down, so
that we don't link the uniform blocks until after we've
merged all the variables. The logic went something like:

Removing the checks for last ssbo member unsized from
the compiler and into the linker, meant doing the check
in the link_uniform_blocks code. However to do that the
array sizing had to happen first, so we knew that the
only unsized arrays were in the last block. But array
sizing required the variable to be merged, otherwise
you'd get two different array sizes in different
version of two variables, and one would get lost
when merged. So the solution was to move array sizing
up, after variable merging, but before uniform block
visiting.
