For floating point ops, these bits determine the "negate?" and "abs?"
modifiers. For integer ops, it turns out they control how sign/zero
extension work, useful for mixing types.

This adds preliminary support for indirect loads of varying arrays and
uniform arrays, bringing a few new tests in shader.indexing.* to
passing, although there remains a number of cases still missing.

Varying arrays sometimes are lowered to a series of directly accessed
varyings (which we handled okay), but when indirectly accessed, they
appear as a single array; we need to handle this as well.

The semantics of this field are not well understood; it is better to
print it unconditionally along with the other unknown state, rather than
silently eat the value. Without this change, some critical state was
being lost in some shaders (notably, the offset for load/store
scratchpad intructions found in shaders that spill registers.)

Commit 624789e370 moved the destruction of types out of atexit() and
made use of a ref count instead. This is useful for avoiding a crash
where drivers such as radeonsi are still compiling in a thread when the app
exits and has not called MakeCurrent to change from the current context.
While the above scenario is technically an app bug we shouldn't crash.
However that change caused another race condition between the shader
compilation tread in radeonsi and context teardown functions.
This patch makes two changes to fix this new problem:
First we explicitly call _mesa_destroy_shader_compiler_types() when destroying
the st context rather than calling it indirectly via _mesa_free_context_data().
We do this as we must call it after st_destroy_context_priv() so that we don't
destory the glsl types before the compilation threads finish.
Next wait for the shader threads to finish in si_destroy_context() this
also means we need to call context destroy before destroying the queues
in si_destroy_screen().
Fixes: 624789e370 ("compiler/glsl: handle case where we have multiple users for types")
