+Summary: [PATCH] dont create temporaries for other temporaries
+in handle_loaded_temps, we create temporaries for everything on the stack
+whenever an instruction might modify data.
+This optimization marks some variables as temporaries -- they will only be
+written to once. handle_loaded_temps will not copy them into a new
+variable, as they will never be clobbered.
+This saves 2% of the variables we create when compiling corlib. It reduces
+the size of the code by 10 kb.
