anv: Flush caches prior to PIPELINE_SELECT on all gens

The programming note that says we need to do this still exists in the
SkyLake PRM and, from looking at the bspec, seems like it may apply to
all hardware generations SNB+.  Unfortunately, this isn't particularly
clear cut since there is also language in the bspec that says you can
skip the flushing and stall to get better throughput.  Experimentation
with the "Car Chase" benchmark in GL seems to indicate that some form of
flushing is still needed.  This commit makes us do the full set of
flushes regardless of hardware generation.  We can always reduce the
flushing later.

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.

  - Make the _bits functions take a gen_device_info.

  - Reformat header to appear human-written not machine-generated.
  - Sort gens from high to low. Newest gens should come first because,

Fast copy blit was primarily added to support Yf/Ys detiling.

We've already required Kernel 3.6 on Gen6+ since Mesa 9.2 (May 2013,
commit 92d2f5acfadea672417b6785710c9e8b7f605e41).  It seems reasonable
