Avoid PLT for external calls when attribute nonlazybind is used. Differential Revision: https://reviews.llvm.org/D39065 llvm-svn: 317292

Improve testcase. We now test that pic and static produce different results for bar. The function names were demangled. The attributes are written inline. llvm-svn: 323680

GOTPCREL references must always use RIP. With -fno-plt, global value references can use GOTPCREL and RIP must be used. Differential Revision: https://reviews.llvm.org/D45460 llvm-svn: 329765
