Small (really small!) C++ exception handling examples work on 32-bit x86 now. This change disables the use of .seh_* directives in WinException when CFI is not in use. It also uses absolute symbol references in the tables instead of imagerel32 relocations. Also fixes a cache invalidation bug in MMI personality classification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238575 91177308-0d34-0410-b5e6-96231b3b80d8
