I can confirm that applying r257832 onto the llvm 3.8.0 sources does
indeed introduce the regression in handling of -mllvm
-inline-threshold=500 for the c-ray 1.1 benchmark. It would be nice if
the underlying problem in the cost-handling for that benchmark could
be addressed as well (since few users will be aware of the -mllvm
-inline-threshold= workaround).
