b3b1397664 tcg: Convert extrh_i64_i32 to TCGOutOpUnary 
At the same time, make extrh_i64_i32 mandatory.  This closes a hole
in which move arguments could be cast between TCGv_i32 and TCGv_i64.

1e6fec9dd9 tcg: Convert extrl_i64_i32 to TCGOutOpUnary 
Drop the cast from TCGv_i64 to TCGv_i32 in tcg_gen_extrl_i64_i32
an emit extrl_i64_i32 unconditionally.  Move that special case
to tcg_gen_code when we find out if the output is live or dead.
In this way even hosts that canonicalize truncations can make
use of a store directly from the 64-bit host register.

Use TCGOutOpUnary instead of TCGOutOpBswap because the
flags are not used with this opcode; they are merely
present for uniformity with the smaller bswaps.

8726c7d799 tcg: Do not require both rotr and rotl from the backend 
Many host architectures do not implement both rotate right
and rotate left and require the compiler to negate the
shift count to rotate the opposite direction.  We have been
requiring the backend to perform this transformation.
Do this during opcode expansion so that the next patch
can drop support where possible in the backend.
