Adam Nemet 4ddb8c01b1 [GVN, OptDiag] Print the interesting instructions involved in missed load-elimination
[recommitting after the fix in r288307]

This includes the intervening store and the load/store that we're trying
to forward from in the optimization remark for the missed load
elimination.

This is hooked up under a new mode in ORE that allows for compile-time
budget for a bit more analysis to print more insightful messages.  This
mode is currently enabled for -fsave-optimization-record (-Rpass is
trickier since it is controlled in the front-end).

With this we can now print the red remark in http://lab.llvm.org:8080/artifacts/opt-view_test-suite/build/SingleSource/Benchmarks/Dhrystone/CMakeFiles/dry.dir/html/_org_test-suite_SingleSource_Benchmarks_Dhrystone_dry.c.html#L446
