faf276b4c8 freedreno/ir3/ra: split building regs/classes and conflicts
Split out the construction of registers and classes (which is the same
on all gens) from setting up conflicts.  Prep to re-work how we setup
conflicts on a6xx+ which merged half/full register file.

90f7d12236 freedreno/ir3/ra: pick higher numbered scalars in first pass
Since we are re-assigning the scalars anyways in the second pass, assign
them to the highest free reg in the first pass (rather than lowest) to
allow packing vecN regs as low as possible.

Note this required some changes specifically for tex instructions with a
single component writemask that is not necessarily .x, as previously
these would get assigned in the first RA pass, and since they are still
scalar, we'd end up w/ some r47.* and other similarly way-to-high
assignments after the 2nd pass.

1da90ca9bf freedreno/ir3/ra: compute register target from liveranges
Using the output of the first pass isn't ideal, as it can bake in the
losses from fragmentation which the scalar pass is intended to fill in.
This gets worse when we start using "vectorish" instructions, due to
higher use of vecN values.

Instead, we can just use the outputs of the liveness analysis to get a
more accurate # of maximum live values at any point.

6347c2ea89 freedreno/ir3/ra: add def/use iterators
Decouple the messy logic of figuring out vreg names defined/used by an
instruction from the logic of what to do about it by introducing
iterators.  There is still *some* array vs ssa special casing in
ra_block_compute_live_ranges(), but less than before.  And this will
avoid introducing a second copy of the def/use logic in a following
patch which uses the liveranges to calculate the maximum # of live
values (which is the optimal target for max physical register window
to round-robin within).

This gets rid of an extra level of split/collect, which shouldn't be
needed.  And interferes with scheduler trying to put tex-prefetches
after inputs but before other instructions.  (Otherwise it would have
to figure out which split/collects need to go before the tex-prefetch)

07885cbcdb CI: Add native Windows VS2019 build
Adds a native build of Mesa using Meson with the Visual Studio 2019
toolchain on a Windows host.

Though Docker is supported on Windows, Docker-in-Docker is not possible,
nor are podman and skopeo available. We handle this by creating the
container from a shell-executor Windows machine, which gives us a native
PowerShell that we can execute Docker from. This attempts to do the same
copy-from-upstream-or-create-if-not-exists optimisation as the
ci-templates do for our Linux builds, albeit open-coded in PowerShell.

The Mesa build itself is executed inside a container, using Meson and
Ninja.

Unlike other stages TCS outputs not read by the TES cannot always
be demoted to globals e.g. when they are read by other TCS
invocations.

We were not taking these outputs into account when packing which
could result in other outputs being assigned to the same location.

Here we make sure to gather information on these outputs and group
them together when packing.

LLVM 11 (master) is more affected than previous versions, but
based on the small impact with LLVM 9/10, I decided to emit it
unconditionally.

d548384fc6 ac/nir: use llvm.amdgcn.rsq for nir_op_frsq
Instead of emitting 1.0 / sqrt(x) which includes a slow division that
LLVM doesn't always optimize even if the metadata is correctly set.
