<pre>The ARM setjmp/longjmp exception handling assumes that the frame pointer
register is r7. This is not true for all targets, some use r11 instead.
It also assumes that a frame pointer is being used, but doesn't guarantee this.
We should probably emit a frame pointer for any function using the SjLj
intrinsics.</pre>
