runtime: handle nil ptr load/store in arm software floating point
We cannot let a real panic start there, because there is C code
on the stack, and worse, there is an assembly frame with a
saved copy of the registers and we have no idea which ones
are pointers.
Instead, detect the nil ptr load/store and return out of the C
and assembly into a stub that will start the call to sigpanic.
Fixes GOARM=5 build.
