vm: fix crash due to stale frame pointer
In some cases, calls made while processing insns in uc_vm_execute_chunk can
lead to realloc of vm->callframes without reloading the current frame pointer.
This was observed with I_ADD (which can call an object's tostring method).
Instead of playing whac-a-mole with insns affecting the frame pointer, let's
reload it whenever necessary.

[further refactor to avoid redundant null pointer checks, fix native function
callframe stop condition while looking for exception handler]
