It is intended to be used for a family of personality functions that have similar IR preparation requirements. Typically when interoperating with MSVC personality functions, bits of functionality need to be outlined from the main function into helper functions. There is also usually more than one landing pad per invoke, which does not match the LLVM IR landingpad representation. None of this is implemented yet. This change just adds a new enum that is active for *-windows-msvc and delegates to the EH removal preparation pass. No functionality change for other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224625 91177308-0d34-0410-b5e6-96231b3b80d8
