[PATCH 1/2] tcg: add dup_const_tl wrapper

[Philipp Tomsich]

dup_const always generates a uint64_t, which may exceed the size of a
target_long (generating warnings with recent-enough compilers).

To ensure that we can use dup_const both for 64bit and 32bit targets,
this adds dup_const_tl, which wraps dup_const and legalises the
truncation to target_long by casting it to target_long.
