A utility class to create COFF dllimport GOT symbols (__imp_*) and PLT stubs.
If an instance of this class is attached to a JITDylib as a fallback definition generator, PLT stubs and dllimport __imp_ symbols will be generated for external symbols found outside the given jitdylib. Currently only supports x86_64 architecture.

DefinitionGenerators should override this method to insert new definitions into the parent JITDylib.
K specifies the kind of this lookup. JD specifies the target JITDylib being searched, and JDLookupFlags specifies whether the search should match against hidden symbols. Finally, Symbols describes the set of unresolved symbols and their associated lookup flags.
Implements llvm::orc::DefinitionGenerator.
