This patch will allow dynamic libraries to call into the fiber support functions introduced in
https://reviews.llvm.org/D54889

I will use these functions in openmp/tools/archer/ompt-tsan.cpp to handle OpenMP tasks as fibers.
The libarcher.so library built from this file is loaded dynamically by the OpenMP runtime.
