It represents a wasm global that could have an initial value.   Several symbols could point to a given global.  For example `__stack_pointer` and `__stack_pointer_alias` could both point to global 0, and in this case we would only want to write a single global to the final output and have both those symbols resolve to the same value when used in relocations.
