This makes sure to use a no-op swizzle while iteratively rendering each
level of a mipmap otherwise we may loose components and effectively
apply the swizzle twice by the time these levels are sampled.

Previously we would emit the comparison, emit an AND to mask off extra
bits from the comparison result, then convert the result to float. Now,
do the comparison, then use a cleverly constructed SEL to pick either
0.0f or 1.0f.

Add Intel driver hook for glGetTexImage to accelerate the case of reading
texture image into a PBO. This case gets huge performance gains by using
GPU BLIT directly to PBO rather than GPU BLIT to temporary texture followed
by memcpy.
No regressions on Piglit tests with Intel driver.
Performance gain (1280 x 800 FBO, Ivybridge):
glGetTexImage + glMapBufferRange with patch 1.45 msec
glGetTexImage + glMapBufferRange without patch 4.68 msec

- Fix compile after Eric's change to drop the tiling argument
to intel_miptree_create_for_bo.
- Add GL_TEXTURE_3D to blacklisted texture targets to prevent Piglit
regressions.
- Squash in several whitespace and coding style fixes.
We need to invalidate the live intervals when inserting new

These used to call different math emitters (brw_math vs. brw_math2).
Now that they both call gen6_math, they're virtually identical.
When unrolling SIMD16 to multiple SIMD8 operations, we should take care
not to apply sechalf to brw_null_reg for src1. Otherwise, we'd end up
with BRW_ARF_NULL + 1 as the register number, and I'm not sure if that's
valid.

Our existing functions, brw_math and brw_math2, had unclear roles:
Gen4-5 used brw_math for both unary and binary math functions; it never
used brw_math2. Since operands are already in message registers, this
is reasonable.
Gen6+ used brw_math for unary math functions, and brw_math2 for binary
math functions, duplicating a lot of code. The only real difference was
that brw_math used brw_null_reg() for src1.
This patch improves brw_math2's assertions to allow both unary and
binary operations, renames it to gen6_math(), and drops the Gen6+ code
out of brw_math().

Thread switching on control flow instructions is a documented workaround
for Gen4-5 errata. As far as I can tell, it hasn't been needed since
Sandybridge. Thread switching is not free, so in theory this may help
performance slightly.
Flow control instructions with the "switch" flag cannot be compacted, so
removing it will make these instructions compactable. (Of course, we
still have to implement compaction for flow control instructions...)
