When we've changed draw_find_shader_output to return -1 instead
of 0 on non found attribs we broke the default behavior of
draw, which was to always redirect those to the first (0th) slot.
To preserve that behavior if draw_emit_vertex_attr notices a
mismatched vertex attrib, it just redirects it to the first slot
(instead of trying to use negative index in an array).

In traditional multisampled framebuffer rendering, color samples must be
explicitly resolved via BlitFramebuffer before doing the scaled blitting
of the framebuffer. So, scaled blitting of a multisample framebuffer
takes two separate calls to BlitFramebuffer.
This patch implements the functionality of doing multisampled scaled
resolve using just one BlitFramebuffer call. Important changes involved
in this patch are listed below:
- Use float registers to scale and offset texture coordinates.
- Change offset computation to consider float coordinates.
- Round the scaled coordinates down to nearest integer.
- Modify src texture coordinates clipping to account for scaling..
- Linear filter is not yet implemented in blorp. So, don't use
blorp engine to do single sampled scaled blitting.
V3: Fix nearest filtering issue in scaled blits. Makes failing piglit
fbo-blit-stetch test and framebuffer_blit_functionality_magnifying_blit.test
in gles3 CTS pass.
Observed no piglit, gles3 CTS regressions on sandybridge & ivybridge with
this patch.

tests to start crashing with assertion failures. That was before my
desktop tanked and the test run died completely.
Remove hash function on shader variants. Nature of variants limits them to a
small number and thus its more efficient to just do a memory compare of the
actual shader structures rather than compute and compare hashes.
This is my attempt at fixing this as the CVE is making RH security team

Pre-Haswell hardware doesn't support an arbitrary restart index, and
instead compares the index buffer value against 0xFF for byte-size
buffers, 0xFFFF for short-size buffers, or 0xFFFFFFFF for unsigned
integer buffers.
OpenGL allows the restart index to be an arbitrary unsigned integer.
When comparing against byte/short types, the index buffer value should
be promoted to a full 32-bit integer before doing the comparison. The
restart index is /not/ supposed to be masked to byte/short size.
This means that with certain restart indexes, the comparison should
always fail. For example, a restart index of 0xF000FFFF should never
match any byte/short index buffer values due to the extra high bits.
We must not enable hardware primitive restart in such a case. For now,
fall back to software primitive restart as it's the simplest fix. In
the future, we could detect restart indexes that will never match and
skip both hardware and software primitive restart.

The derived state approach currently used (_RestartIndex) doesn't work:

The existing code also fails to obey the GL 4.3 rules which say that
FIXED_INDEX takes precedence over normal primitive restart.

"If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not
taking a type parameter, including all of the *Draw* commands other
than *DrawElements*."
The OpenGL ES 3.0 specification agrees by omission:
