Revert "i965/vec4: Use MOV, not OR, to set URB write channel mask bits."

This reverts commit af13cf609f4257768ad8b80be8cec7f2e6ca8c81, which
appears to cause huge performance problems on Ivybridge.  I'd missed
that the FFTID bits are in the low byte.  The documentation doesn't
indicate that the URB write message header actually wants FFTID - it
just labels those bits as "Reserved."  But it appears necessary.

This does slightly more than revert the original change: originally,
Broadwell had separate code generation, which used MOV, and this patch
only changed it for Gen4-7.  Now that both are unified, reverting this
also makes Broadwell use OR.  Which should be fine.

Revert "configure: Fix --enable-XX-bit flags by moving LT_INIT where it should"

The commit was resolving an issue where libtool will not setup the
environment correctly when one explicitly provides --enable-{32,64}-bit
at configure time. It was caused due to the "-m32,64" C{,XX}FLAGS being

trying to handle 32/64 bit build ourselves it may be better to delegate
it to the builder/maintainer. The latter should now know better which is
the correct(most appropriate) method.

i965: Store uniform constant values in a gl_constant_value instead of float

The brw_stage_prog_data struct previously contained an array of float pointers
to the values of parameters. These were then copied into a batch buffer to
upload the values using a regular assignment. However the float values were
also being overloaded to store integer values for integer uniforms. This can
break if x87 floating-point registers are used to do the assignment because
the fst instruction tries to fix up invalid float values. If an integer
constant happened to look like an invalid float value then it would get
altered when it was copied into the batch buffer.

This patch changes the pointers to be gl_constant_value instead so that the
assignment should end up copying without any alteration. This also makes it
more obvious that the values being stored here are overloaded for multiple
types.

There are some static asserts where the values are uploaded to ensure that the
size of gl_constant_value is the same as a float.

ra: don't consider nodes for spilling we don't need to

Previously, we would consider any optimistically colored nodes for
spilling. However, spilling any optimistically colored nodes below the
node that we failed to color on the stack wouldn't help us make
progress, since it wouldn't help with allowing us to find a color for
the node currently failing to get colored. Only consider nodes
which were above the failing node on the stack for spilling, which
simplifies the logic, and comment the code better so people know what's
going on here.

No shader-db changes with BRW_MAX_GRF reduced to 90 (or with the normal
number of GRF's).

ra: make the p, q test more efficient

We can store the q total that pq_test() would've calculated in the node
itself, updating it when we add a node to the stack. This way, we only
have to walk the adjacency list when we push a node on the stack (i.e.
when the p, q test succeeds) instead of every time we do the p, q test.

No difference in shader-db run times, but I'm keeping this in because
the q total that it calculates will also be used in the next few commits.

ra: cleanup the public API

Previously, there were 3 entrypoints into parts of the actual allocator,
and an API called ra_allocate_no_spills() that called all 3. Nobody
would ever want to call any of the 3 entrypoints by themselves, so
everybody just used ra_allocate_no_spills(). So just make them static
functions, and while we're at it rename ra_allocate_no_spills() to
ra_allocate() since there's no equivalent "with spills," because the
backend is supposed to handle spilling.
