Currently, if you compile with -fomit-frame-pointer, the frame record and frame pointer are still maintained (i.e. There is no way to get the behaviour you are asking for!).This patch fixes that. It also makes sure that if you ask for no frame pointers in leaf functions then they are not generated there unless LR gets clobbered in the leaf for some reason. (I have testcases here to check for that.) OK to commit to trunk?
