Restrict all operands to registers. All constants will be forced
into registers by the middle-end. Removing the difference in how
immediate integers were encoded will allow more code to be shared
between 32-bit and 64-bit operations.

This was removed from tcg_target_reg_alloc_order and
tcg_target_call_iarg_regs on the assumption that it
was the stack. This was incorrectly copied from i386.
For tci, the stack is R15.
By adding R4 back to tcg_target_call_iarg_regs, adjust the other
entries so that 6 (or 12) entries are still present in the array,
and adjust the numbers in the interpreter.

As noted in several comments, 8 regs is not enough for 32-bit
to perform calls, as currently implemented. Shortly, we will
rearrange the encoding which will make 32 regs impossible.

The existing check was incomplete:
(1) Only applied to two of the 7 stores, and not to the loads at all.
(2) Only checked the upper, but not the lower bound of the stack.
Doing this at compile time means that we don't need to do it
at runtime as well.

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.
