Paolo Bonzini 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.

/*
* For most instructions that use the same element size for reads and
* writes, we can use real gvec vector expansion, which potantially uses
* real host vector instructions. As they only work up to 64 bit elements,
* 128 bit elements (vector is a single element) have to be handled
* differently. Operations that are too complicated to encode via TCG ops
* are handled via gvec ool (out-of-line) handlers.
*
* As soon as instructions use different element sizes for reads and writes
* or access elements "out of their element scope" we expand them manually
* in fancy loops, as gvec expansion does not deal with actual element
* numbers and does also not support access to other elements.
*
* 128 bit elements:
* As we only have i32/i64, such elements have to be loaded into two
* i64 values and can then be processed e.g. by tcg_gen_add2_i64.
*
* Sizes:
* On s390x, the operand size (oprsz) and the maximum size (maxsz) are
* always 16 (128 bit). What gvec code calls "vece", s390x calls "es",
* a.k.a. "element size". These values nicely map to MO_8 ... MO_64. Only
* 128 bit element size has to be treated in a special way (MO_64 + 1).
* We will use ES_* instead of MO_* for this reason in this file.
*
* CC handling:
* As gvec ool-helpers can currently not return values (besides via
* pointers like vectors or cpu_env), whenever we have to set the CC and
* can't conclude the value from the result vector, we will directly
* set it in "env->cc_op" and mark it as static via set_cc_static()".
* Whenever this is done, the helper writes globals (cc_op).
