i965/vec4: Improve src_reg/dst_reg conversion constructors.
This simplifies the src_reg/dst_reg conversion constructors using the
swizzle utils introduced in a previous patch. It also makes them more
useful by changing their semantics slightly: dst_reg(src_reg) used to
set the writemask to XYZW if the src_reg swizzle was anything other
than XXXX, which was almost certainly not what the caller intended if
the swizzle was non-trivial. After this patch the same components
that are present in the swizzle will be enabled in the resulting
writemask.
src_reg(dst_reg) used to set the first components of the swizzle to
the enabled components of the writemask and then replicate the last
enabled component to fill the swizzle, which, in cases where the
writemask didn't have exactly the first n components set, would in
general not be compatible with the original dst_reg. E.g.:
| ADD(tmp, src_reg(tmp), src_reg(1));
would *not* do what one would expect (add one to each of the enabled
components of tmp) if tmp didn't have a writemask of the described
form (e.g. YZ, YW, XZW would all fail). This pattern actually occurs
in many different places in the VEC4 back-end, it's a wonder that it
hasn't caused piglit failures until now. After this patch
src_reg(dst_reg) will construct a swizzle with each enabled component
at its natural position (e.g. Y at the second position, Z at the
third, and so on). The resulting swizzle will behave like the
identity when used in any instruction with the original writemask.
I've manually verified that *none* of the callers of both conversion
constructors were relying on the previous broken semantics. There are
no piglit regressions on any generation.

llvmpipe: use global llvm context for PIPE_SUBSYSTEM_EMBEDDED
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.

i965: Factor out logic to build a send message instruction with indirect descriptor.
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

i965: Set nr_params to the number of uniform components in the VS/GS path.
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.

glsl: Annotate as_foo functions that the this pointer cannot be NULL
We use the idiom
ir_foo *x = y->as_foo();

all over the place. GCC generates some quite lovely code for this.
One such example:
340a5b: 83 7d 18 04 cmpl $0x4,0x18(%rbp)
340a5f: 0f 85 06 04 00 00 jne 340e6b

340a68: 0f 84 fd 03 00 00 je 340e6b
This case used as_expression() (ir_type_expression is 4). Note that it
checks the ir_type, then checks that the pointer isn't NULL. There is
some disconnect in GCC around the condition in the as_foo functions.
return ir_type == ir_type_##TYPE ? (ir_##TYPE *) this : NULL; \
It believes "this" could be NULL, so it emits check outside the function
just for fun.
This patch uses assume() to tell GCC that it need not bother with extra
NULL checking of the pointer returned by the as_foo functions.
