  Changed paths:
    M clang/lib/CodeGen/CodeGenModule.cpp
    A clang/test/Interpreter/inline-virtual.cpp

  Log Message:
  [CodeGen] Keep track of eagerly emitted globals

An inline virtual function must be emitted, but we need to remember
it and emit the same definition again in the future in case later
LLVM optimizations stripped it from the Module. The added test case
shows the problem; before this patch, it would fail with:
    Symbols not found: [ _ZN1AD0Ev, _ZN1AD1Ev ]
