[WebAssembly] Added a .globaltype directive to .s output.
Summary:
Assembly output can use globals like __stack_pointer implicitly,
but has no way of indicating the type of such a global, which makes
it hard for tools processing it (such as the MC Assembler) to
reconstruct this information.
The improved assembler directives parsing (in progress in
https://reviews.llvm.org/D53842) will make use of this information.
Also deleted code for the .import_global directive which was unused.
New test case in userstack.ll
