StackSafetyAnalysis determines whether stack-allocated variables are guaranteed to be safe from memory access bugs and enables the removal of certain unneeded instrumentations. (hwasan enables StackSafetyAnalysis in https://reviews.llvm.org/D108381) Test updates: * asan-stack-safety.ll: test the -asan-use-stack-safety=1 default * lifetime-uar-uas.ll: switch to an indexed store to prevent StackSafetyAnalysis from optimizing out instrumentation for %c * alloca_vla_interact.cpp: add a load to prevent StackSafetyAnalysis from optimizing out `__asan_alloca_poison` for the VLA `array` * scariness_score_test.cpp: add -asan-use-stack-safety=0 to make a load of a `__asan_poison_memory_region`-poisoned local variable fail as intended. * other .ll tests: add -asan-use-stack-safety=0 Reviewers: kstoimenov, eugenis, vitalybuka Reviewed By: kstoimenov Pull Request: https://github.com/llvm/llvm-project/pull/77210
