Olivier Galibert 982df3c1a5 llvmpipe: Color slot interpolation can be flat or perspective, not linear. 
Fixes a bunch of glsl 1.10 interpolation piglit tests.

José Fonseca 6cf7245f69 llvmpipe: Trim the fragment shader cached based on LLVM IR instruction count. 
Number of fragment shader variants is not very representative of the
memory used by LLVM, neither is number of shader instructions, as often
texture sampling constitutes most of the generated code.

This change adds an additional trim criteria: least recently used
fragment shader variants will be freed until the total number of LLVM IR
instruction falls below a specified threshold.

José Fonseca f32c7232a8 llvmpipe,draw,gallivm: Ensure we don't walk beyond the end of the shader variant list. 
u_simple_list.h uses a sentinel element, and not a NULL element. So
ensure list is not empty when reducing the list of shader variants.

Something I noticed while trying to free variants more aggressively.

Brian Paul efc82aef35 gallivm/llvmpipe: squash merge of the llvm-context branch 
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.

use of the fragment shader in the wide point stage.

José Fonseca 95c18abb03 llvmpipe: Unbreak Z32_FLOAT. 
Z32_FLOAT uses <4 x float> as intermediate/destination type,
instead of <4 x i32>.

The necessary bitcasts got removed with commit
5b7eb868fd

Also use depth/stencil type and build contexts consistently, and
make the depth pointer argument a ordinary <i8 *>, to catch this
sort of issues in the future (and also to pave way for Z16 and
Z32_FLOAT_S8_X24 support).
