[PATCH v6 00/23] tcg: Better handling of constants

[Richard Henderson]

Changes for v6:

Minor rebase conflict fixed.

Changes for v5:

Moved the clearing of the hash table from the end of compilation
to the beginning of compilation.  We skip the former when we long
jump out of the translator loop, e.g. touching a code page that
is unmapped.
