Previously, we performed conversions from float->uint by a two step
process: float->int->uint. However, on platforms that use saturating
conversions (e.g. i965), this didn't work, because if the source value
was larger than the maximum representable int (0x7fffffff), then
converting it to an int would clamp it to 0x7fffffff.
This patch just adds the new opcode; further patches will adapt
optimization passes and back-ends to use it, and then finally the
ast_to_hir logic will be modified to emit the new opcode.

This patch modifies blorp blits (which are used for MSAA) to properly
account for clipping of source coordinates. Previously, if we
detected the possibility of source clipping, we would fall back to the
blit meta-op, which doesn't support MSAA and is very slow for depth
and stencil buffers.
Fixes piglit tests
"EXT_framebuffer_multisample/clip-and-scissor-blit" on i965/Gen6+.
Also substantially speeds up the Humble Bundle V game "Psychonauts" on
Gen6+ (without this patch, the game's depth buffer blits use the slow
blit meta-op).

When drawing a depth image the fragment shader also needs to emit the
current raster color.
The new piglit drawpix-z test exercises this.
NOTE: This is a candiate for the 8.0 branch.
This patch updates .gitignore files to account for the new build
artifacts introduced by the following commits:
ae376f0 glx/tests: Rename test as glx-test
8fecdcc mesa/tests: Add tests for _mesa_lookup_enum_by_{name,nr} functions
a29ad2b mesa/tests: Add tests for the generated dispatch table
When the video buffer turns out to be larger than

Haiku targets the Pentium or higher processor.
To ensure compatibility we can do march 586 and
mtune 686. Mesa will still use sse however if
the cpu supports it (and the stack is properly
aligned). These flags only effect the internal
compiler optimizations.
Previously, rbug_*.c would fail to compile with incomplete prototype
errors when make was run from the command line on my machine. My IDE
always built fine, and still does after this patch (Netbeans 7.1.2).
Most of the includes from files in gallium/auxiliary/rbug/* were
assuming an rbug/ subdirectory, while the headers are actually in the
same directory as the .c files.
The build error was also previously a problem for me on Ubuntu 11.10
and Mint 12.
Fixes build for the following configuration: ./autogen.sh
--enable-debug --enable-texture-float --with-gallium-drivers=r600
--with-dri-drivers=radeon --enable-r600-llvm-compiler

In single precision, 1.5707963 becomes 1.5707962513 which is too
small. However, 1.5707964 becomes 1.5707963705 which is just right.
The value 1.5707964 is already used in asin.ir.
NOTE: This is a candidate for stable release branches.
