r600g: check NULL return from u_upload_alloc

Like done in si_state_draw.c::si_draw_vbo

u_upload_alloc can fail, i.e. set output param *ptr to NULL, for 2 reasons:
alloc fails or map fails. For both there is already a fprintf/stderr in
radeon_create_bo and radeon_bo_do_map.

In src/gallium/drivers/ it is a common usage to just avoid to crash by doing
a silent check. But defer fprintf where the error comes from, libdrm calls.

genxml: New generated header genX_bits.h (v6)

genX_bits.h contains the sizes of bitfields in genxml instructions,
structures, and registers. It also defines some functions to query those
sizes.

isl_surf_init() will use the new header to validate that requested
pitches fit in their destination bitfields.

What's currently in genX_bits.h:

  - Each CONTAINER::Field from gen*.xml that has a bitsize has a macro
    in genX_bits.h:

        #define GEN{N}_CONTAINER_Field_bits {bitsize}

  - For each set of macros whose name, after stripping the GEN prefix,
    is the same, genX_bits.h contains a query function:

      static inline uint32_t __attribute__((pure))
      CONTAINER_Field_bits(const struct gen_device_info *devinfo);

v2 (Chad Versace):
  - Parse the XML instead of scraping the generated gen*_pack.h headers.

v3 (Dylan Baker):
  - Port to Mako.

v4 (Jason Ekstrand):
  - Make the _bits functions take a gen_device_info.

v5 (Chad Versace):
  - Fix autotools out-of-tree build.
  - Fix Android build. Tested with git://github.com/android-ia/manifest.
  - Fix macro names. They were all missing the "_bits" suffix.
  - Fix macros names more. Remove all double-underscores.
  - Unindent all generated code. (It was floating in a sea of whitespace).
  - Reformat header to appear human-written not machine-generated.
  - Sort gens from high to low. Newest gens should come first because,
    when we read code, we likely want to read the gen8/9 code and ignore
    the gen4 code. So put the gen4 code at the bottom.
  - Replace 'const' attributes with 'pure', because the functions now
    have a pointer parameter.
  - Add --cpp-guard flag. Used by Android.

i965: Require Kernel 3.6 for Gen4-5 platforms.

We've already required Kernel 3.6 on Gen6+ since Mesa 9.2 (May 2013,
commit 92d2f5acfadea672417b6785710c9e8b7f605e41).  It seems reasonable
to require it for Gen4-5 as well, bumping the requirement from 2.6.39.

This is necessary for glClientWaitSync with a timeout to work, which
is a feature we expose on Gen4-5.  Without it, we would fall back to an
infinite wait, which is pretty bad.

See kernel commit 172cf15d18889313bf2c3bfb81fcea08369274ef in 3.6+.

glsl: fix spelling of embedded in comment

glsl: fix lower jumps for returns when loop is inside an if

Previously we would just escape the loop and move everything
following the loop inside the if to the else branch of a new if
with a return flag conditional. However everything outside the
if the loop was nested in would still get executed.

Adding a new return to the then branch of the new if fixes this
and we just let a follow pass clean it up if needed.

  " When instance names are present on matched block names, it is

Therefore, no cross linking validation is needed for the instance name

This patch will make that no link error will be reported on a program

glsl/shader_cache: restore evicted shader keys

Even though the programs themselves stay in cache and are loaded, the
shader keys can be evicted separately. If that happens, unnecessary
compiles are caused that waste time, and no matter how many times the
program is re-run, performance never recovers to the levels of first
hot cache run. To deal with this, we need to refresh the shader keys

An easy way to currently observe this is running Deux Ex, then piglit
and Deux Ex again, or deleting just the cache index. The later is
causing over a minute of lost time on all later Deux Ex runs, with this
