History
Akira Hatanaka 5506e22865 [InstCombine] Do not insert a GEP instruction before a landingpad instruction. 
InstCombiner::visitGetElementPtrInst was using getFirstNonPHI to compute the
insertion point, which caused the verifier to complain when a GEP was inserted
before a landingpad instruction. This commit fixes it to use getFirstInsertionPt
instead.
