x86: evaluation destination should be after load of source in RA [DO NOT MERGE]
In almost most cases working with Register Allocator we must first load source and then evaluate the destination. In this particular case for byte-code shl-int/2addr v10, v10 we first find a destination (memory) then load source (v10 -> physical register) and generate a shift operation on memory. This is ok for this bytecode but RA thinks that v10 is in register (we loaded source) and this is incorrect because updated value in memory and physycal register is not up to date.
