Shared landing pads run into trouble with SJLJ, as the dispatch table is mapped to call sites, and merging the pads will throw that off. There needs to be a one-to-one mapping of landing pad exception table entries to invoke call points. Detecting the shared pad during lowering of SJLJ info insn't sufficient, as the dispatch function may still need separate destinations to properly handle phi-nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80530 91177308-0d34-0410-b5e6-96231b3b80d8
