RFR(S): 8029668: Kithcensink crashed with guarantee(Assembler::is_simm13(disp)) failed: Do not match large constant offsets

A quick fix for the problem, since we’re under time constraints. Bailout if we try to reference a stack location that we can't encode.  Note that, MachSpillCopy emission already behaved this way.
