78659ade40 glsl: use enum glsl_interface_packing in more places. (v2)
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.

27b9481d03 glsl: Add an option to clamp block indices when lowering UBO/SSBOs
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.

aebb0e0186 glsl: make ssbo predicate return true when in a GLSL 430 or ESSL 310 shader
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.

35f8488668 glsl: keep track of ssbo variable being accessed, add access params
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.
