tcg: Fix generation of dupi_vec for 32-bit host
The definition of INDEX_op_dupi_vec is that it operates on units of tcg_target_ulong -- in this case 32 bits. It does not work to use this for a uint64_t value that happens to be small enough to fit in tcg_target_ulong. Fixes:d2fd745fe8
Fixes:db432672dc
