This will be removed at the end of the transition, but add some tracking
plus asserts to help ensure that lowering passes are called at the
correct point (pre or post deref instruction lowering) as passes are
converted and the point where lower_deref_instrs() is called is moved.

It's redundant with nir_shader::info::stage.

According to section 14.6 of the Vulkan specification:
"When sample shading is enabled, the x and y components of FragCoord
reflect the location of the sample corresponding to the shader
invocation."
So add a boolean parameter to the lowering pass to select this behavior
when we need it.

Otherwise we rewrote the fadd to use itself, causing crashes in
validation. Instead, start after the last use like we should.
A brown paper bag fix. Fixes crashes in several Vulkan tests.

nir_lower_wpos_ytransform() is great for OpenGL, which allows
applications to choose whether their coordinate system's origin is
upper left/lower left, and whether the pixel center should be on
integer/half-integer boundaries.
Vulkan, however, has much simpler requirements: the pixel center
is always half-integer, and the origin is always upper left. No
coordinate transform is needed - we just need to add <0.5, 0.5>.
This means that we can avoid using (and setting up) a uniform.
I thought about adding more options to nir_lower_wpos_ytransform(),
but making a new pass that never even touched uniforms seemed simpler.
v2: Use normal iterator rather than _safe variant (noticed by Matt).
