glcpp mingw failing in the following way:
```
49/56 mesa:compiler+glcpp / glcpp test (unix) FAIL 3.39s exit status 1
50/56 mesa:compiler+glcpp / glcpp test (oldmac) FAIL 3.41s exit status 1
51/56 mesa:compiler+glcpp / glcpp test (bizarro) FAIL 3.42s exit status 1
52/56 mesa:compiler+glcpp / glcpp test (windows) FAIL 3.45s exit status 1
```
The test failed because on mingw, the stderr will comes after stdout,
but all the expect files, the stderr is coming first,
so we flush(stderr) first to makesure stderr out before stdout
The failing example:

Because we use unaligned dispatches, 1D launches only use 8 threads per
wave. Converting to 2D and fixing up launch IDs in the prolog
significantly increases occupancy.

zink_bo_create can run into a heap-use-after-free when the bo is still
referencing an batch_state from an older destroyed context. In order to
fix this, every context gives back their batch_states to the zink, where
they can be reused from for new contexts.

This is safe to do in all circumstances due to the age of the hardware.
(we don't have UBOs, just constant registers with automatic OOB checks)
R500 hardware doesn't have standard adress register in fragment shaders
and while we have the loop register which we in theory can use for indirect
access, this is currently not possible to wire through NIR. So anytime
there is an indirect uniform array access in a loop, we end with a if
ladder with size depending on the size of the uniform array. The two worst
behaving apps here are glamor and some GTK shaders, both of which are
sometimes ending over the 512 instructions limit. Flattening the if
ladders helps a LOT, so we can get into the instruction limit in most
cases (all glamor shaders are OK now). So just enable the flattening by
setting all load_ubo_vec4 with ACCESS_CAN_SPECULATE.

No changes for R300/R400 because there we don't have control flow

The same regression for the few GTK shaders that happens with the R500
nir fcsel lowering also happens here due to the
nir_move_vec_src_uses_to_dest.

We can't call nir_lower_bool_to_float too early, because some other
passes like nir_opt_peephole_select will blow up, but we can still do
some selected parts to enable some optimiazions at a later point
(like fcsel(a,b,0) into fmul), etc.
No change in shader-db with RV370 or RV530 at this point.

Right now this is done in the backend so move it up to NIR. Doing this
in the backend is easier, as at that time we can have a better idea
about when we hit the hardware limits of three different TMP sources,
however moving this to NIR allows for some optimizations. Specifically,
at this time if we decide we actually have to lower we still have the
info if we have plain fcsel for which we can save the comparison and
emit flrp only. During translation to TGSI all of fcsel, fcsel_gt, and
fcsel_ge translate to CMP so at that point the comparison is always needed.

The hurt shaders are some GTK shaders where there is some bad
interaction with nir_move_vec_src_uses_to_dest. This is known and might
be improved later by thweking the pass more.

We do ffloor by default for adress register load so no need to do it
explicitly. This needs to happen after int lowering, otherwise we get
ftrunc by default as a bonus. This is mostly for wined3d.
