The issue we're running into when running CTS is that glsl types are
deleted while builtins depending on them are not.
This happens because on one hand we have glsl types ref counted, but
builtins are not. Instead builtins are destroyed when unloading libGL
or explicitly calling glReleaseShaderCompiler().
This change removes almost entirely any dealing with glsl types
ref/unref by letting the builtins deal with it instead. In turn we
introduce a builtin ref count mechanism. Each GL context takes a
reference on the builtins when compiling a shader for the first time.
It releases the reference when the context is destroyed. It can also
explicitly release those when glReleaseShaderCompiler() is called.
Finally we also take a reference on the glsl types when loading libGL
to avoid recreating glsl types too often.
v2: Ensure we take a reference if we don't have one in link step (Lionel)

_mesa_glsl_has_builtin_function is used to determine whether any variant
of a builtin are available, for the purpose of enforcing the GLSL ES
3.00+ rule that overloads or overrides of builtins are disallowed.
However the builtin_builder contains information on all builtins,
irrespective of parse state, or versions, or extension enablement. As a
result we would say that a builtin existed even if it was not actually
available.
To resolve this, first check if at least one signature is available for
a builtin before returning true.

Builtins are created once and allocated using their own private ralloc
context. When reparenting IR that includes builtins, we might be steal
bits of builtins. This is problematic because these builtins might now
be freed when the shader that includes then last is disposed. This
might also lead to inconsistent ralloc trees/lists if shaders are
created on multiple threads.
Rather than including builtins directly into a shader's IR, we should
include clones of them in the ralloc context of the shader that
requires them. This fixes double free issues we've been seeing when
running shader-db on a big multicore (72 threads) server.
v2: Also rename _mesa_glsl_find_builtin_function_by_name() to better
reflect how this function is used. (Ken)

to detect the presence. This allows these functions to be tested using
