Guanzhong Chen e15dc95466 [wasm-ld] Add __global_base symbol to mark the value of --global-base 
Summary:
This is needed for address sanitizer on Emscripten. As everything in
memory starts at the value passed to --global-base, everything before
that can be used as shadow memory.

This symbol is added so that the library for the ASan runtime can know
where the shadow memory ends and real memory begins.

This is split from D63742.
