This reverts commit 60bf0f05b4.
It seems round_mode behaves differently in some cases depending on the
instruction/slot. Reverting it for now.

We should just set the bits of functionality that we support; the
GL/ES1/ES2 flags in extensions.c will take care of advertising the
appropriate extensions for the current API.
This enables the GL_EXT_texture_compression_dxt1 extension on ES1/ES2
when libtxc_dxtn is installed or the force_s3tc driconf option is set.
The main extension code set this up properly, but the ES-specific code
failed to do so.
Otherwise, the extension strings reported by es1_info, es2_info, and
glxinfo all remain the same.
This patch manually disables the ARB_framebuffer_object bit on ES
to preserve the behavior of 1c0f5d8324.
v2: Rebase, fix the i915 Makefile, and unconditionally set the
OES_draw_texture bit as core Mesa will only apply it to ES1 now.

If the primitive restart index and the primitive type can

For newer hardware we disable the VBO module's software handling
of primitive restart. We now handle primitive restarts in
brw_handle_primitive_restart.
The initial version of brw_handle_primitive_restart simply calls
vbo_sw_primitive_restart, and therefore still uses the VBO
module software primitive restart support.

When considering which components of a variable were killed by an
assignment, constant propagation would previously just use the write
mask of the assignment. This worked if the LHS of the assignment was
simple, e.g.:
v.xy = ...; // (assign (xy) (var_ref v) ...)
But it did the wrong thing if the LHS of the assignment involved an
array indexing operator, since in this case the write mask is always
(x):
v[i] = ...; // (assign (x) (deref_array (var_ref v) (var_ref i)) ...)
In general, we can't predict which vector component will be selected
by array indexing, so the only safe thing to do in this case is to
kill the entire variable.

The spec requires that samplers be initialized to 0. Since this
differs from the 1-to-1 mapping of samplers to texture units assumed
by ARB assembly shaders (and the gl_program structure), be sure to
propagate this date from the gl_shader_program to the gl_program.

While it doesn't have the same warning in the simulator as in gen7,
let's emit it out of paranoia. We wouldn't want our resolves of some
previous clear to get clamped to some current clamping value.
Suggested-by: pretty much everyone
When doing fast clears, a fulsim warning said that the batch was being
emitted without the viewport set up. While the fast clear pass I was
looking at doesn't use the clear value, the later resolves which also
didn't set up the vieport would trigger the same. It's not obvious
from the error message whether it meant "fast clear value gets clamped
to something you haven't defined" or "fast clear value doesn't get
clamped, and I saw it was out of the current (uninitialized) range,
and you probably wanted it clamped to that (uninitialized) range". Be
paranoid and assume the first case.
