Subject: DenseMap: assert that we have found a bucket before we try to insert into it.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=3bbdddf527c762085802544665d6e77471ea035b;p=oota-llvm.git

DenseMap: assert that we have found a bucket before we try to insert into it.

This silences literally dozens of analyzer warnings on LLVM (since DenseMap
is such a commonly-used class).
