Compiling my shader-db with the gallium noop driver is 6.8% faster now.
Theoretical stat-based results are below, which don't always reflect real
results.
When compiling Heaven shaders with the gallium noop driver,
134610 calloc calls are removed.
134610 / ralloc count = 6%, so it's roughly the equivalent of 6% of
the cost of all ralloc calls that's removed. The shift from calloc to
linear_alloc increases ralloc calls by 0.4%, so the approximate reduction
is 6% -> 0.4% overhead change.

This separates the GLSL IR exec_node from the NIR exec_node,
so that we can change the GLSL IR version.

Since we have now switched all drivers to using NIR and therefore
the NIR based uniform linker this param never needs to be set to
true so remove it.

The spec requires unused uniform block to be set as active in the
program resource list. To support this we tell opt dead code not to
remove them. However we can mark them as unused internally and
avoid unnecessarily state changes.
This change is also required for the folowing clean-up patch.

I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.
No difference in OglBatch7 (n=20).

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.
