Richard Henderson 23586e2674 tcg: Optimize spills of constants ... While we can store constants via constrants on INDEX_op_st_i32 et al, we weren't able to spill constants to backing store. Add a new backend interface, tcg_out_sti, which may store the constant (and is allowed to fail). Rearrange the temp_* helpers so that we only attempt to directly store a constant when the temp is becoming dead/free. Backports commit 59d7c14eeff8d2ad7f61aed86ce5a176113bc153 from qemu		2018-02-25 01:45:29 -05:00
