tcg: Optimize some forms of deposit.
If the deposit replaces the entire word, optimize to a move.
If we're inserting to the top of the word, avoid the mask of arg2
as we'll be shifting out all of the garbage and shifting in zeros.
If the host is 32-bit, reduce a 64-bit deposit to a 32-bit deposit
when possible.
