llvm-mirror/test/Transforms/RewriteStatepointsForGC/base-vector-inseltpoison.ll
Philip Reames 93763f7273 [rs4gc] don't duplicate existing values which are provably base pointers 
RS4GC needs to rewrite the IR to ensure that every relocated pointer has an associated base pointer. The existing code isn't particularly smart about avoiding duplication of existing IR when it turns out the original pointer we were asked to materialize a base pointer for is itself a base pointer.

This patch adds a stage to the algorithm which prunes nodes proven (with a simple forward dataflow fixed point) to be base pointers from the list of nodes considered for duplication. This does require changing some of the later invariants slightly, that's probably the riskiest part of the change.
