nv50/ir: use sched control codes for gm107 builtins
Yes, IMUL/IMAD require dependency barriers and we should
definitely replace these instructions by XMAD but the
different flags need to be figured out. Note that XMAD only
supports 16-bits integers.

This makes use of scheduling control codes which are very useful
for improving the instruction pipelining.
This patch will increase performance on Maxwell GPUs by, at least,
x1.5 up to x3.5 for some benchmarks.
Although this has been fairly well tested, I would not be suprised
if someone hit a corner case somewhere. That way, the scheduler
is enabled by default but it can be deactivated by using
NV50_PROG_SCHED=0.

It's actually useless to insert those texture barriers post RA
because the current control code (ie. st 0x0) will wait for all
dependencies before issuing a new instruction.

i965/vec4: emit correctly load_inputs for 64bit data
For dvec3 and dvec4 types, a single GRF do not have enough space to
allocate two inputs from two different vertices (SIMD4x2).
So the GRF only contains first two components for the two vertices, and
the next GRF has the remaining components.
We want to put all the components for the same vertex in the same
register. Thus, we do a shuffle to reorder the data.

i965/vec4: use attribute slots for first non payload GRF
As part of the payload setup, setup_attributes is called with the first
GRF that can be used for the attributes (first ones are used for
uniforms for example) and returns the first GRF that is not part of the
payload. Before this patch, it adds directly the number of attributes.
But as with 64-bit attributes can consume more than one slot, that is
not valid anymore. This patch change the addition to use the number of
slots consumed.
gen >= 8 would not be affected, as they use the scalar mode. For that
case, the vs configuration is done at fs_visitor::assign_vs_urb_setup.

main/buffers: take into account FRONT_AND_BACK on ReadBuffer
From OpenGL 3.1 spec, section 4.3.1 "Reading Pixels", page 190 (203 PDF)
"When READ FRAMEBUFFER BINDING is zero, i.e. the default
framebuffer, src must be one of the values listed in table 4.4,
including NONE . FRONT_AND_BACK , FRONT , and LEFT refer to the
front left buffer."
There is an equivalent text on OpenGL 4.5 spec, section 18.2.1
"Selecting Buffers for Reading", page 502 (524 PDF), so the behaviour
is still the same.

main/buffers: update error handling on DrawBuffers for 4.5
Before 4.5, GL_BACK was not allowed as a value of bufs. Since 4.5 it
is allowed under some circumstances:
From the OpenGL 4.5 specification, Section 17.4.1 "Selecting Buffers
for Writing", page 493 (page 515 of the PDF):
"An INVALID_ENUM error is generated if any value in bufs is FRONT,
LEFT, RIGHT, or FRONT_AND_BACK . This restriction applies to both
the de- fault framebuffer and framebuffer objects, and exists
because these constants may themselves refer to multiple buffers, as
shown in table 17.4."
And on page 492 (page 514 of the PDF):
"If the default framebuffer is affected, then each of the constants
must be one of the values listed in table 17.6 or the special value
BACK . When BACK is used, n must be 1 and color values are written
into the left buffer for single-buffered contexts, or into the back
left buffer for double-buffered contexts."
This patch keeps the same behaviour if OpenGL version is < 4. We
assume that for 4.x this is the intended behaviour, so a fix, but for
3.x the intended behaviour is the already in place.
