Oliver Stannard dff114b356 [ARM] Optimise non-ABI frame pointers (#110286) ...

With -fomit-frame-pointer, even if we set up a frame pointer for other
reasons (e.g. variable-sized or over-aligned stack allocations), we
don't need to create an ABI-compliant frame record. This means that we
can save all of the general-purpose registers in one push, instead of
splitting it to ensure that the frame pointer and link register are
adjacent on the stack, saving two instructions per function.
