egl: Simplify the "driver" interface

"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

loader/dri3: Use local blits and local buffers when resizing

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.

gallivm/ppc64le: allow environmental control of Altivec code generation

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.

gallivm/ppc64le: adjust VSX code generation control.

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.

i965: Validate "Special Requirements for Handling Double Precision Data Types"

I did not implement:

   CNL's restriction on 64-bit int + align16, because I don't think
   we'll ever use this combination regardless of hardware generation.

   The restriction on immediate DF -> F conversions, because there's no
   reason to ever generate that, and I don't even know how DF -> F
   conversions are supposed to work in Align16 since (1) the dst stride
   must be 1, but (2) the dst stride would have to be 2 for src and dst
   strides to be aligned.

i965: Fix and enable forgotten validation test

I seem to have forgotten I still had work to do.

i965: Only insert error message if not already present

Some restrictions require something like strides to match between src
and dest. For multi-source instructions, I'd rather encapsulate the
logic for not inserting already present errors in ERROR_IF than
open-coding it multiple places.

i965: Avoid validation error when src1 is not present

There can be no violation of the restriction that source offsets are
aligned if there is only one source offset.

i965: Remove validate_reg()

Replaced by the assembly validator, and in fact gets in the way of
writing tests for the assembly validator.

i965: Add and use STRIDE and WIDTH macros
