an instruction out of the if-statement will allow
nir_opt_peephole_select to convert the whole thing to a bcsel.

Currently only floating point compares and adds are supported.  Adding
support for integer will be a challenge due to integer overflow.  There
are a couple possible solutions, but they may not apply to all
architectures.

iris: Fix blits with S8_UINT destination

For depth and stencil blits, we always want the main mask to be Z, and
the secondary pass mask to be S.  If asked to blit Z+S to S, we should
handle the blit in the second pass which properly gets the stencil
resources.

Before, we were trying to handle S as the main mask, and accidentally
blitting a Z source to a S destination, which doesn't work out well.

Fixes Piglit's "framebuffer-blit-levels {draw,read} stencil" tests.
