755bf9e514 tcg: Adjust tcg_register_jit for const
We must change all targets at once, since all must match
the declaration in tcg.c.

ffd0e50736 tcg: Adjust TCGLabel for const
Change TCGLabel.u.value_ptr to const, and initialize it with
tcg_splitwx_to_rx.  Propagate const through tcg/host/ only
as far as needed to avoid errors from the value_ptr change.

8b5c2b6260 tcg: Move tcg epilogue pointer out of TCGContext
This value is constant across all thread-local copies of TCGContext,
so we might as well move it out of thread-local storage.

74a117906b tcg: Remove TCG_CT_REG
This wasn't actually used for anything, really.  All variable
operands must accept registers, and which are indicated by the
set in TCGArgConstraint.regs.

The union is unused; let "regs" appear in the main structure
without the "u.regs" wrapping.

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.
