Oliver Stannard 1a5239251e [ARM] r11 is reserved when using -mframe-chain=aapcs (#86951) ...

When using the -mframe-chain=aapcs or -mframe-chain=aapcs-leaf options,
we cannot use r11 as an allocatable register, even if
-fomit-frame-pointer is also used. This is so that r11 will always point
to a valid frame record, even if we don't create one in every function.
