Hi Cameron,

> This was a 16% speedup running loops on test-suite + SPEC2000.

dense map iterators are invalidated when new values are inserted.  Did you
audit the code to check that this is not a problem?  If in doubt, you could
build LLVM with expensive checks enabled and check that nothing blows up in
the testsuite.

Ciao,

Duncan.
