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.
