This changes the order of basic blocks to be equal to the order of code in the

Some of the existing code is needlessly complicated. The basic principle
should be: control-flow opcodes emit branches to properly terminate the
current block, _unless_ the current block already has a terminator (which
happens if and only if there was a BRK or CONT).
This also fixes a bug where multiple terminators were created in a block.

In core profile, we support up to 16 viewports. However, in the
majority of cases, only 1 of them is actually used - we only need
the others if the last shader stage prior to the rasterizer writes
gl_ViewportIndex.
Processing all 16 viewports adds additional CPU overhead, which hurts
CPU-intensive workloads such as Glamor. This meant that switching to
core profile actually penalized Glamor to an extent, which is
unfortunate.
This patch tracks the number of relevant viewports, switching between
1 and ctx->Const.MaxViewports if gl_ViewportIndex is written. A new
BRW_NEW_VIEWPORT_COUNT flag tracks this. This could mean re-emitting
viewport state when switching, but hopefully this is offset by doing
1/16th of the work in the common case. The new flag is also lighter
weight than BRW_NEW_VUE_MAP_GEOM_OUT, which we were using in one case.
According to Eric Anholt, x11perf -copypixwin10 performance improves by
11.5094% +/- 3.10841% (n=10) on his Skylake.

Previously, we were saving off the last nir_block in a vtn_block before
moving on so that we could find the nir_block again when it came time to
handle phi sources. Unfortunately, NIR's control flow modification code is
inconsistent when it comes to how it splits blocks so the block pointer we
saved off may point to a block somewhere else in the shader by the time we
get around to handling phi sources. In order to get around this, we insert
a nop instruction and use that as the logical end of our block. Since the
control flow manipulation code respects instructions, the nop will keeps
its place like any other instruction and we can easily find the end of our
block when we need it.
This fixes a bug triggered by a couple of vkQuake shaders.

HiZ buffers can be multisampled and, on Broadwell and earlier, simply using
interleaved multisampling with a compression block size of 8x4 samples
yields the correct HiZ surface size calculations. Unfortunately,
choose_msaa_layout was rejecting multisampled HiZ buffers because of format
checks. Now that we have a simple helper for determining if a format
supports multisampling, that's an easy enough issue to fix.
