  Log Message:
  -----------
  [lld][WebAssembly] Don't apply data relocations at static constructor time

Instead, export `__wasm_apply_data_relocs` and `__wasm_call_ctors`
separately.

This is required since user code in a shared library (such as static
constructors) should not be run until relocations have been applied to
all loaded libraries.
