So far we were checking ARB_shader_image_load_store is supported as
requirement to expose GLES 3.1.
But when this extension functionality was added in GLES 3.1 spec, it
was relaxed, and one of its requirements, the support for formatless
writing, was not included.
So this means that a driver that support all the extension
functionality except formatless writing, could expose GLES 3.1, but it
couldn't expose the extension itself (nor GL 4.2, which requires fully
implementation of the extension).
v2:
- Add the same exposure treatment to ARB_shader_image_size (Ilia).
v3:
- Remove dependency for OES_texture_buffer (Ilia).
- Check image resources for GLES 3.1 (Ilia).
v4:
- Check for MaxImageUniforms in compute shader (Ilia).
- Check for max combined image uniforms/ssbo (Ilia).
v5:
- Remove ARB_shader_image_load_store from check (Ilia).
- ARB_shader_image_store and ARB_shader_image required for
ARB_ES3_1_compatibility (Ilia).

The GLSL spec says it's an error if a shader statically writes to these
2 variables.
Until this commit, Mesa refused to link a shader if it had an unused
function writing to one of these variables while another (used) function
wrote to the other.
This commit adds an option to perform dead function elimination after
the intra-stage linking step but before performing these checks.

This replaces some new/delete uses with malloc/free.
This is more consistent with most of the other glsl IR code but
more importantly it allows the game "Battle Block Theater" to
start working on some mesa drivers. The game overrides new and
ends up throwing an assert and crashing when it sees this
function calling new [0].
Note: The game still crashes with radeonsi due to similar conflicts
with LLVM.

Clang has a warning about overloading virtuals that triggers when a
derived class defines a virtual function that's an overload of
function in the base class. This kind of thing:
struct chart; // let's pretend this exists
struct Base
{
virtual void* get(char* e);
};
struct Derived: public Base {
virtual void* get(chart* e); // typo, we wanted to override the same function
};
The solution is to use
using Base::get;
to be explicit about the intention to reuse the base class virtual.
We hit this a lot with out glsl ir_hierarchical_visitor visitor
pattern, so let's adds some 'using' to calm down the compiler.
