7d10d8e076 tcg: Move i into each for loop in liveness_pass_1 
Use per-loop variables instead of one 'i' for the function.

No need to expand to i64 to perform the add.
This is smaller on a loongarch64 host, e.g.

	bstrpick_d  r29, r24, 31, 0
	add_d       r28, r28, r29

	add_w       r28, r27, r24
	sltu        r29, r28, r24

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.
