Auto merge of #112000 - wesleywiser:safestack, r=Amanieu
Add support for LLVM SafeStack Adds support for LLVM [SafeStack] which provides backward edge control flow protection by separating the stack into two parts: data which is only accessed in provable safe ways is allocated on the normal stack (the "safe stack") and all other data is placed in a separate allocation (the "unsafe stack"). SafeStack support is enabled by passing `-Zsanitizer=safestack`. [SafeStack]: https://clang.llvm.org/docs/SafeStack.html cc `@rcvalle` #39699
