From: Philipp Tomsich <[email protected]> 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 either maps back to dup_const (for 64bit targets) or provides a similar implementation using 32bit constants.
