Found while trying to optimize an application.
Not observed to help performance on i965, but should at least reduce
the memory usage of such textures a bit.

If the DRM_VC4_GET_TILING ioctl isn't present then we can't tell
if a dmabuf bo is tiled or linear, so will always assume it's
linear.
By not advertising tiled formats in this situation we ensure the
assumption is correct.
This fixes a bug where most attempts to render a gl wayland client
under weston will result in a client side abort.

"Driver" isn't a great word for what this layer is, it's effectively a
build-time choice about what OS you're targeting. Despite that both of
the extant backends totally ignore the display argument, the old code
would only set up the backend relative to a display.
That causes problems! One problem is it means eglGetProcAddress can
generate X or Wayland protocol when it tries to connect to a default
display so it can call into the backend, which is, you know, completely
bonkers. Any other EGL API that doesn't reference a display, like
EGL_EXT_device_query, would have the same issue.
Fortunately this is a problem that can be solved with the delete key.

Avoid freeing buffers holding new back content
(with GLX_SWAP_COPY_OML and GLX_SWAP_EXCHANGE_OML)
Prevously that would have resulted in back buffer content becoming
incorrect after a swap, although I haven't managed to trigger such a
situation yet.

When a drawable is resized, and we fill the resized buffers, with data
from the old buffers, use a local blit if there is a local buffer (back or
fake front), and we have local blitting capability.

In check_os_altivec_support(), allow control of Altivec (first PPC vector
instruction set) code generation via a new environmental control,
GALLIVM_ALTIVEC, which is expected to take on a value of 1 or 0.
The default is to enable Altivec code generation.
This environmental control of Altivec code generation is initially
available only #ifdef DEBUG.

In lp_build_create_jit_compiler_for_module(), advance the minimum
version of LLVM for VSX code generation to 4.0; this is the minimum
revision at which several known VSX code generation bugs are fixed:
https://llvm.org/bugs/show_bug.cgi?id=25503 (fixed in 3.8.1)
https://llvm.org/bugs/show_bug.cgi?id=26775 (fixed in 3.8.1)
https://llvm.org/bugs/show_bug.cgi?id=33531 (fixed in 4.0)
An llc performance bug introduced in LLVM 4.0,
https://llvm.org/bugs/show_bug.cgi?id=34647
is still pending as of LLVM 5.0, but only has a pronounced effect on
one of the Piglit tests: ext_transform_feedback-max-varyings.
All changes tested via Piglit.
