[GlobalISel] Fix insertion of stack-protector epilogue
* Tell the StackProtector pass to generate the epilogue instrumentation
when GlobalISel is enabled because GISel currently does not implement
the same deferred epilogue insertion as SelectionDAG.
* Update StackProtector::InsertStackProtectors() to find a stack guard
slot by searching for the llvm.stackprotector intrinsic when the
prologue was not created by StackProtector itself but the pass still
needs to generate the epilogue instrumentation. This fixes a problem
when the pass would abort because the stack guard AllocInst pointer
was null when generating the epilogue -- test
CodeGen/AArch64/GlobalISel/arm64-irtranslator-stackprotect.ll.
