textureGather() returns the four taps that would have been filtered
together to produce the value that ordinary texturing operations
would return. As such, it should access the same data, so we can use
either interchangeably when we're only checking for residency and not
returning the actual data.
This allows us to mask out some unneeded registers.

This splits a single texture-with-residency operation into two halves,
one which returns texture data, and another which queries residency.
We're currently using this only for a shadow sampling workaround,
but the technique is more broadly applicable, if we ever wanted.

Minor adjustments to formatting of the copyright line, but keep
dates and holders. "Authors" entries that could be
obtained via Git logs were also removed.
The license in brw_disasm.c and elk_disasm.c don't match directly
any SPDX pattern I could find, so kept as is.

Most of the time with nir_def_rewrite_uses_after, you want to rewrite after the
replacement. Make that the default thing to be more ergonomic and to drop
parent_instr uses.
We leave nir_def_rewrite_uses_after_instr defined if you really want the old
signature with an arbitrary after point.
Via Coccinelle patch:
@@
expression a, b;
@@
-nir_def_rewrite_uses_after(a, b, b->parent_instr)
+nir_def_rewrite_uses_after_def(a, b)
Followed by a bunch of sed.
