There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.
The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.
We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

Although the glsl_types.h stores this in a bitfield,
we should hide that from everyone else. Hide the cast
in an accessor method and use the enum everywhere.
This makes things a bit nicer in gdb, and improves type
safety.
v2: fix a few pieces of interface I missed that caused some
piglit regressions.

This prevents array overflow when the block is actually an array of UBOs or
SSBOs. On some hardware such as i965, such overflows can cause GPU hangs.

I can't tell whether this actually matters, but we're creating function
signatures with this predicate, so it should probably match when SSBO's
are available.

Currently any access params (coherent/volatile/restrict) are being lost
when lowering to the ssbo load/store intrinsics. Keep track of the
variable being used, and bake its access params in as the last arg of
the load/store intrinsics.
If the variable is accessed via an instance block, then 'variable'
points to the instance block variable and not the field inside the
instance block that we are accessing. In order to check access
parameters for the field itself we need to detect this case and keep
track of the corresponding field struct so we can extract the specific
field access information from there instead.
