Most cases seem harmless, though that might not always be the case. Maybe
one day we can get gcc to complain about these and fix them throughout
the code, but until then let's silence them.

There's 2 reasons why we'd want to use the global context:
1) There still seems to be one memory "leak" left when using multiple llvm
contexts (it is not a true leak as the memory disappears into some still
addressable pool but nevertheless the memory consumption grows). See
http://cgit.freedesktop.org/~jrfonseca/llvm-jitstress/
2) These contexts get kinda big - even when disposing modules etc. after
compiling a shader the LLVMContext can easily be over 100kB. So when there's
lots of llvm contexts arounds it adds up.
The downside is that at least right now this is absolutely not thread safe,
so this only works safely in environments where multiple pipe contexts are not
used concurrently.

This is currently not a problem because the vec4 visitor happens to
mask out unused components from the destination, but it might become
an issue when we start using atomics without writeback message. In
any case it seems sensible to set it again here because the
consequences of setting the wrong writemask (random graphics memory
corruption) are difficult to debug and can easily go unnoticed.

This is going to be useful because the Gen7+ uniform and varying pull
constant, texturing, typed and untyped surface read, write, and atomic
generation code on the vec4 and fs back-end all require the same logic
to handle conditionally indirect surface indices. In pseudocode:
| if (surface.file == BRW_IMMEDIATE_VALUE) {
| inst = brw_SEND(p, dst, payload);
| set_descriptor_control_bits(inst, surface, ...);
| } else {
| inst = brw_OR(p, addr, surface, 0);
| set_descriptor_control_bits(inst, ...);
| inst = brw_SEND(p, dst, payload);
| set_indirect_send_descriptor(inst, addr);
| }
This patch abstracts out this frequently recurring pattern so we can
now write:
| inst = brw_send_indirect_message(p, sfid, dst, payload, surface)
| set_descriptor_control_bits(inst, ...);
without worrying about handling the immediate and indirect surface
index cases explicitly.

Both do_vs_prog and do_gs_prog initialize brw_stage_prog_data::nr_params to
the number of uniform *vectors* required by the shader rather than the number
of uniform components, contradicting the comment. This is inconsistent with
what the state upload code and scalar path expect but it happens to work until
Gen8 because vec4_visitor interprets it as a number of vectors on construction
and later on overwrites its original value with the number of uniform
components referenced by the shader.
Also there's no need to add the number of samplers, they're not actually
passed in as uniforms.
