Do not print inferred submodules explicitly in __inferred_module.map

Otherwise including a header in your source file that is not included by
framework's umbrella header will silently add an empty submodule with that
name.

is automatically translated to
@import Foo.NotInModule;

which then would have succeeded because the inferred module map
contained an empty submodule called NotInModule.

Moved operator delete to public area to appease gcc and conform to C++ standard.

Fix leak introduced in r194610, found by LSan.

LSan folks: LSan pointed to
    #0 0x4953e0 in operator new[](unsigned long) llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc:64
    #1 0x7fb82af5372f in clang::RewriteRope::MakeRopeString(char const*, char const*) llvm/tools/clang/lib/Rewrite/Core/RewriteRope.cpp:796
instead of to the actual leak, which made tracking this down slower than
it could have been.

Make RewriteRope less confusing for me. No intended behavior change.
