When looking up known glsl_type instances in the various hash tables, we
end up leaking the key instances used for the lookup, as the glsl_type
constructor allocates memory on the global mem_ctx. This patch changes
glsl_type to manage its own memory, which fixes the leak and also allows
getting rid of the global mem_ctx and its mutex.

Adds new INT16, UINT16 and FLOAT16 base types.
The corresponding GL types for half floats were reused from the
AMD_gpu_shader_half_float extension. The int16 and uint16 types come from
NV_gpu_shader_5 extension.
This adds the builtins and the lexer support.
To avoid a bunch of warnings due to cases not handled in switch, the
new types have been added to a few places using same behavior as
their 32-bit counterparts, except for a few trivial cases where they are
already handled properly. Subsequent patches in this set will provide
correct 16-bit implementations when needed.
v2: * Use FLOAT16 instead of HALF_FLOAT as name of the base type.
* Removed float16_t from builtin types.
* Don't copy 16-bit types as if they were 32-bit values in
copy_constant_to_storage().
* Use get_scalar_type() instead of adding a new custom switch
statement.

The ARB_bindless_texture spec says:
"Samplers are represented using 64-bit integer handles."
and,
"Images are represented using 64-bit integer handles."
It seems simpler to always consider sampler and image types
as 64-bit unsigned integer.
This introduces a temporary workaround in _mesa_get_uniform()
because at this point no flag are used to distinguish between
bound and bindless samplers. This is going to be removed in a

So far we have been checking that interface block definitions had matching
matrix layouts by comparing the definitions of their fields, however, this
does not cover the case where the interface blocks are defined with
mismatching matrix layouts but don't define any field with a matrix type.
In this case Mesa will not fail to link because none of the fields will
inherit the mismatching layout qualifier.
This patch fixes the problem in the same way we fixed it for packing layout
information: we add the the layout information to the interface type and then
we check it matches during the uniform block linking process.

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.
