4695bebc79 nir: Drop nir_dest
Instead, we replace every use of it with nir_def.  Most of this commit
was generated by sed:

   sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp

A few manual fixups were required in lima and the nir_legacy code.

3863280399 nir: Add and use nir_tex_src_ssa
This makes texture instructions a lot less annoying to construct, especially in
cases where the deref-based helpers don't work.

I only converted core NIR, not the drivers. Since it was by hand.

Since 624e799cc3 ("nir: Drop nir_ssa_def::name and nir_register::name"), SSA

0f25bb8283 nir: Add helpers for lazy var creation.
This should make writing some lowering/meta code easier.  It also keeps
the num_inputs/outputs updated, when sometimes passes forgot to do so (for
example, nir_lower_input_attachments updated for one of the two vars it
creates).  The names of the variables change in many cases, but it's
probably nicer to see "VERT_ATTRIB_POS" than "in_0" or whatever.

I've only converted mesa core (compiler and GL), not all the driver meta
code.

b474ed1f3a nir, ir3: Add option to use unscaled FragCoord for input attachments
When rendering a scaled tile, we need to use the original, hardware
FragCoord when accessing input attachments that are on-tile (i.e. were
rendered to in a previous subpass) because they are also scaled in the
same way that FragCoord is scaled. For input attachments that aren't
already on-tile, however, we need to use the fixed gl_FragCoord. Add a
new intrinsic and a bitfield of input attachments which should use it.

ff05137c2d nir: introduce and use nir_component_mask
The BITFIELD_MASK() macro is intended for using with actual bitfields,
not with nir_component_mask_t. This means we do some extra work to
handle values that are invalid for nir_component_mask_t in the first
place.

This eliminates some warnings on Clang, where the compiler complains
about casting UINT32_MAX to UINT16_MAX.

27f0c3c15e radv: Make FragCoord a sysval
load_fragcoord is already handled in common code for radeonsi, so we
don't need to do anything to handle it. However, there were some passes
creating NIR with the varying, so we switch them over to the sysval. In
the case of nir_lower_input_attachments which is used by both radv and
anv, we add handling for both until intel switches to using a sysval.
