When building in a MSYS2 Mingw-w64 environment Mesa3D sets wrong default build options which inevitably lead to build failure.

intel/error2aub: add support for platforms without PPGTT

nir: Factor out most of the algebraic passes C code to .c/.h.

Working on the algebraic implementation, I was being driven nuts by my
editor not highlighting and handling indentation for the C code.  It turns
out that it's basically not pass-specific code, and we can move it over to
the relevant .c file.  Replaces 30KB of code with 34KB of data on my i965
build.  No perf diff on shader-db (n=3)

nir: Skip emitting no-op movs from the builder.

Having passes generate these is just making more work for copy
propagation (and thus probably calling more optimization passes)
later.  Noticed while trying to debug nir_opt_algebraic()
top-to-bottom having O(n^2) behavior due to not finding new matches in
replacement code.

pan/midgard: Replace mir_is_live_after with new pass

Now that we have live_out calculated per block as metadata, calculating
liveness of an instruction at a given point in the program becomes O(n)
to the size of the block worst-case, rather than O(n) the program.

pan/midgard: Invalidate liveness for mir_is_live_after

Callers should have liveness info ready. Ideally we'd have a nice
metadata tracking framework like NIR to handle this automatically, but
for now this will allow us to make forward progress... when we're about
to do something with liveness, invalidate everything ahead to force a
clean calculation.

This will allow us to explicitly invalidate liveness analysis results so

There are unfortunately two distinct liveness analysis passes in the

solving data flow equations, and one awful (but simple) pass used for
dead code elimination and bundling based on an abstract walk of the AST.

Let's move RA's pass into shared code so we can work on unifying.
