Move all logic related to selecting the bitcode compiler and linker
into a new file and dynamically test required compiler flags. This
also adds -fcuda-rdc for Clang trunk as previously attempted in https://reviews.llvm.org/D44992
which fixes the build.

As a result this change also enables building the library by default
if all prerequisites are met.
