Further testing revealed two problems when compiling nested
1) The logic I had for cr_save_regno is wrong, resulting in one of my
NOT_INUSE asserts triggering.
2) In some cases the prologue uses in-line saves while the epilogue
uses out-of-line restores. This can lead to restoring regs that
haven't been saved.
