Teresa Johnson 1487747e99 [LTO] Prevent devirtualization for symbols dynamically exported 
Identify dynamically exported symbols (--export-dynamic[-symbol=],
--dynamic-list=, or definitions needed to preempt shared objects) and
prevent their LTO visibility from being upgraded.
This helps avoid use of whole program devirtualization when there may
be overrides in dynamic libraries.

Benchmarking

In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
