Same as VADDCUW and VSUBCUW, overall performance gain but it uses more
TCGop (4 before the patch, 6 after).

c85929b2dd target/ppc: Move VAVG[SU][BHW] to decodetree and use gvec 
Moved the instructions VAVGUB, VAVGUH, VAVGUW, VAVGSB, VAVGSH, VAVGSW,
to decodetree and use gvec with them. For these one the right shift
had to be made before the sum as to avoid an overflow, so add 1 at the
end if any of the entries had 1 in its LSB as to replicate the "+ 1"
before the shift described by the ISA.

These results to me seems to indicate that with gvec the results have a
slower translation but faster execution.

I wasn't expecting such a performance lost in both VPRTYBD and VPRTYBQ,
I'm not sure if it's worth to move those instructions. Comparing the
assembly of the helper with the TCGop they are pretty similar, so
I'm not sure why vprtybd took so much more time.

611bc69bf6 target/ppc: Move V(ADD|SUB)CUW to decodetree and use gvec 
This patch moves VADDCUW and VSUBCUW to decodtree with gvec using an
implementation based on the helper, with the main difference being
changing the -1 (aka all bits set to 1) result returned by cmp when
true to +1. It also implemented a .fni4 version of those instructions
and dropped the helper.

dd8014e4e9 Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-5.2-20200818' into staging 
ppc patch queue 2020-08-18

Here's my first pull request for qemu-5.2, which has quite a few
accumulated things.  Highlights are:

 * Preliminary support for POWER10 (Power ISA 3.1) instruction emulation
 * Add documentation on the (very confusing) pseries NUMA configuration
 * Fix some bugs handling edge cases with XICS, XIVE and kernel_irqchip
 * Fix icount for a number of POWER registers
 * Many cleanups to error handling in XIVE code
 * Validate size of -prom-env data

139c1837db meson: rename included C source files to .c.inc 
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.
