  Log Message:
  -----------
  [ORC] Use dyn_cast to check input type in StaticLibraryDefinitionGenerator.

Replaces an llvm::cast that assumed that all Binary instances were either
Archive or MachOUniversalBinary instances with a dyn_cast. The cast was
triggering an assert in StaticLibraryDefinitionGenerator::Load if that method
was given a path or MemoryBuffer containing a relocatable object file.
Switching to dyn_cast causes the operation to error out with a bad-format
error as expected.
