No need to register function prototypes in the module now that we call
the C function pointer directly -- less LLVM objects lying around.
Limited testing with lp_test_format.

Fixes piglit regression, http://bugs.freedesktop.org/show_bug.cgi?id=32452
NOTE: This is a candidate for the 7.10 branch

Create a constant int pointer to the C function, then cast it to the
function's type. This avoids using trampoline code which seem to be
inadvertantly freed by LLVM in some situations (which leads to segfaults).
The root issue and work-around were found by José.

This branch defines a gallivm_state structure which contains the
LLVMBuilderRef, LLVMContextRef, etc. All data structures built with
this object can be periodically freed during a "garbage collection"
operation.
The gallivm_state object has to be passed to most of the builder
functions where LLVMBuilderRef used to be used.

The function was duplicated.

This fixes the assert added in LLVM 2.8:
assert(getType()->isIntOrIntVectorTy() &&
"Tried to create an integer operation on a non-integer type!")
But it also fixes some subtle bugs, since we should've been doing this
since LLVM 2.6 anyway.
Includes a modified patch from steckdenis@yahoo.fr for the
FNeg instructions in emit_fetch(); thanks for pointing those out.

This allows to do the unpacking of formats that fit in 4 x unorm8 in
parallel, 4 pixels at a time.

They need to grow, and they provide basic functionality which is not
specific to sampling.

Uses code and ideas from Brian Paul.

Refactor the code to make this easier.

util_format_description::fetch_rgba_float
This therefore adds support to half float vertex buffers.

Useful for fetching vertices for formats that are straight arrays.
This reverts commit aa364d091e7e2ef2296fb25f92efc79a8c88f77d.

It's unused and incomplete. Still in git history if necessary in future.

the llvmpipe tgsi translation is a lot more complete than what was in
gallivm so replacing the latter with the former. this is needed since
the draw llvm paths will use the same code. effectively the proven
llvmpipe code becomes gallivm.
