The VCC register is tricky because the SALU views it as 64-bit, but the
VALU views it as 1-bit. In order to deal with this we've added some
special bitcast and binary operations to help convert from the 64-bit
SALU view to the 1-bit VALU view and vice versa.
If you want to change your compiler arguments, just set CFLAGS/CXXFLAGS.
Having Mesa have this separate variable is a great way to have your arguments
not thoroughly propagated to all compiler invocations.

In all current uses, it was appended to CFLAGS, which already had -m32. If
you want to do some other flag supplied to compiler invocations, there's
CFLAGS/CXXFLAGS.

The emit->key.fkey info is only valid if we're generating a fragment shader.
We should not look at it if we're generating a vertex shader.
When generating a vertex shader, the value of emit->key.fkey.num_textures was
garbage and the loop over num_textures would read invalid data. At best
this would cause us to emit an unused constant. At worse, we could segfault.
Just by dumb luck, fkey.num_textures was usually a smallish integer.
NOTE: This is a candidate for the 8.0 branch.

Mesa misses a few checks when compiling on a uclibc system
which cause it to fall back on glibc-ism. This patch
addresses those issues.

The kernel streamout support was supposed to get into 3.3 along
the tiling change and thus use the same kernel version bump of
2.13 to report userspace that streamout register were supported.
This is not what happen. So as streamout kernel support did not
bump the kernel driver version, rely on kernel 2.14 version bump
to know if streamout is enabled or not. Which means you need at
least 3.4 kernel.

Testing shows that the standard JIT engine retrofited with AVX support is quite
stable and as capable to handle AVX instructions as MC-JIT is.
And the old JIT is much more memory efficient, as we don't need to
allocate one engine instance per shader, as we do for MC-JIT due to its
incompleteness.

When X is running it is neccesary for pipe_loader to authenticate with
DRM, in order to be able to use the device.
This makes it possible to run OpenCL programs while X is running.
v2:
- Fix C++ style comments
- Drop Xlib-xcb dependency
- Close the X connection when done
- Split auth code into separate function
