[WebAssembly] Don't include lazy symbols in import table This bug was introduced in: https://reviews.llvm.org/D41304. Add a test for this case. Differential Revision: https://reviews.llvm.org/D41309 llvm-svn: 320872

[WebAssembly] When loading libraries look for companion `.imports` file This allows libraries to supply a list of symbols which are allowed to be undefined at link time (i.e. result in imports). This method replaces the existing mechanism (-allow-undefined-file) used by the clang driver to allow undefined symbols in libc. For more on motivation for this see: https://github.com/WebAssembly/tool-conventions/issues/35 In the long run we hope to remove this features and instead include this information in the object format itself.
