Set the flag via the _mesa_init_gl_program() and NewProgram()
helpers.
In i965 we currently check for the existance of gl_shader_program
to decide if this is an ARB assembly style program or not.
Adding a flag makes the code clearer and will help removes a
dependency on gl_shader_program in the i965 codegen functions.
Also this will allow use to skip initialising sampler units for
linked shaders, we currently memset it to zero again during linking.

Having it here rather than in gl_linked_shader allows us to simplify
the code.
Also it is error prone to depend on the gl_linked_shader for programs
in current use because a failed linking attempt will free infomation
about the current program. In i965 we could be trying to recompile
a shader variant but may have lost some required fields.

This fixes 555 dEQP tests (using the nougat-cts-dev branch), Piglit's
arb_program_interface_query/arb_program_interface_query-resource-query,
and GL45-CTS.program_interface_query.separate-programs-{tess-control,
tess-eval,geometry}. Only one dEQP program interface failure remains.
I would have liked to split this up into several distinct changes, but
I wasn't sure how to do that given thet tangled nature of these issues.
So, the issues:
* We need to treat interface blocks declared as an array of instances
as a single block - removing the outer array. The resource list
entry's name should not include the array length. Properties such
as GL_ARRAY_SIZE should refer to the variable inside the block, not
the interface block's array properties.
* We need to do this prefixing even for structure variables.
* We need to do this for built-ins (such as gl_PerVertex.gl_Position).
* After interface array unwrapping, any variable which is an array
should have [0] appended. It doesn't matter if it's a TCS/TES/GS
input or TCS output - that looked like an attempt to unwrap for
per-vertex variables, but that didn't consider per-patch variables,
and as far as I can tell there's nothing to justify this.
Several Mesa developers have suggested that Issue 16 contradicts the
main specification, but I believe that it doesn't - the main spec just
isn't terribly clear. The main ARB_program_interface query spec says:
"* For an active interface block not declared as an array of block
instances, a single entry will be generated, using the block name from
the shader source.
* For an active interface block declared as an array of instances,
separate entries will be generated for each active instance. The name
of the instance is formed by concatenating the block name, the "["
character, an integer identifying the instance number, and the "]"
character."
Issue 16 says that built-ins should be named "gl_PerVertex.gl_Position",
but several people suggested the second bullet above means that it
should be named "gl_PerVertex[array length].gl_Position".
There are two important things to note. Those bullet points say
"an active interface block", while the others say "variable" or "active
shader storage block member". They also don't mention applying the
rules recursively (unlike the other bullets). Both suggest that
these rules apply to blocks themselves, not members of blocks.
In fact, for GL_UNIFORM_BLOCK queries, we do have "block[0]",
"block[1]", ... resource list entries - so those rules are real,
and actually used. So if they don't apply to block members, then how
should members be named? Unfortunately, I don't see any rules outside
of issue 16 - where the rationale is very unclear. I hope to clarify
the spec in the future.

07fe2d565b introduced a big hack in order to return
NumSubroutineUniforms when querying ACTIVE_RESOURCES for
<shader>_SUBROUTINE_UNIFORM interfaces. However this is the
wrong fix we are meant to be returning the number of active
resources i.e. the count of subroutine uniforms in the
resource list which is what the code was previously doing,
anything else will cause trouble when trying to retrieve
the resource properties based on the ACTIVE_RESOURCES count.
The real problem is that NumSubroutineUniforms was counting
array elements as separate uniforms but the innermost array
is always considered a single uniform so we fix that count
instead which was counted incorrectly in 7fa0250f9.
Idealy we could probably completely remove
NumSubroutineUniforms and just compute its value when needed
from the resource list but this works for now.
