"meson test" starting with version 0.57 is just as capable and easy to
use as QEMU's own TAP driver. All existing options for "make check"
work. The only required code change involves how to mark "slow" tests;
they need to belong to an additional "slow" suite.
The rules for .tap output are replaced by JUnit XML; GitLab is able
to parse that output and present it in the CI pipeline report.

Rename to parts$N_log2. Though this is partly a ruse, since I do not
believe the code will succeed for float128 without work. Which is ok
for now, because we do not need this for more than float32 and float64.
Since berkeley-testfloat-3 doesn't support log2, compare float64_log2
vs the system log2. Fix the errors for inputs near 1.0:

Many qemu softfloat will check floatx80_rounding_precision
even when berkeley testfloat will not. So begin with
floatx80_precision_x, so that's the one we use

With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.
Alternatively you can use a fine-grained dependency, e.g.
target/arm/translate.o: target/arm/decode-neon-shared.inc.c
With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.
The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.
Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files. The editorconfig
file is adjusted.

Re-calling the main make is counter-productive and really messes up
with parallel builds. Just ensure we have built the pre-requisites
before we build the fp-test bits. If the user builds manually just
complain if the parent build hasn't got the bits we need.
