glsl: Switch ast_type_qualifier to a 128-bit bitset.

This should end the drought of bits in the ast_type_qualifier object.
The bitset_t type works pretty much as a drop-in replacement for the
current uint64_t bitset.

The only catch is that the bitset_t type as defined in the previous
commit doesn't have a trivial constructor (because it has a
user-defined constructor), so it cannot be used as union member
without providing a user-defined constructor for the union (which
causes it in turn to be non-trivially constructible).  This annoyance
could be easily addressed in C++11 by declaring the default
constructor of bitset_t to be the implicitly defined one -- IMO one
more reason to drop support for GCC 4.2-4.3.

The other minor change was required because glsl_parser_extras.cpp was
hard-coding the type of bitset temporaries as uint64_t, which (unlike
would have been the case if the uint64_t had been replaced with
e.g. an __int128) would otherwise have caused a build failure, because
the boolean conversion operator of bitset_t is marked explicit (if
C++11 is available), so the bitset won't be silently truncated down to
1 bit in order to use it to initialize the uint64_t temporaries
(yikes).

broadcom/vc4: Remove the retval==usage check in is_format_supported().

This got us into trouble recently, so just remove it entirely.

broadcom/vc4: Add support for YUV textures using unaccelerated blits.

Previously we would assertion fail about having no hardware format.  This
is enough to get kmscube -M nv12-2img working.

broadcom/vc4: Fix double-unrefcounting of prsc->next with shadows.

When we set up the shadow resource we were copying the original resource
as the template, including its prsc->next field.  When we shadowed the
first YUV plane's resource for linear-to-tiled conversion, we would end up
unbalancing the refcount on the shadow resource's destruction.

broadcom/vc4: Add pipe_reference debugging for vc4_bos.

Trying to track down the YUV EGLImage use-after-free, it helps to see what
the mystery objects are that are being refcounted.

broadcom/vc4: Remove dead vc4_bo_set_reference().

It would be broken if NULL was passed to it anyway, since it wouldn't
participate in screen->bo_handles management.

broadcom/vc4: Use pipe_resource_reference in sampler views.

Improves u_debug_refcount output.

broadcom/vc4: Allow importing linear BOs with arbitrary offset/stride.

This is part of supporting YUV textures -- MMAL will be handing us a
single GEM BO with the planes at offsets within it, and MMAL-decided

etnaviv: fix in-place resolve tile count
