c68aaa1892 tcg: Add consistency checks for op definitions
When compiled with CONFIG_DEBUG_TCG, this code looks
for missing, duplicate and wrong entries in the
op definitions.

Errors will raise an assertion at program start
(all checks are done in the initial phase).

The current code contains such errors, at least for
i386 guest on i386 host.

f839394688 Add a --enable-debug-tcg option to configure
This patch allows DEBUG_TCGV to be defined (and also prevents NDEBUG
from being defined) when passing an option to the configure script.
This should help to prevent any accidental changes that enable
DEBUG_TCGV in tcg/tcg.h from being committed in future, and may
help to encourage testing with DEBUG_TCGV enabled.

b9c18f5658 tcg: add a CONST flag to TCG helpers
A const function only reads its arguments and does not use TCG
globals variables. Hence a call to such a function does not
save TCG globals variabes back to their canonical location.
