wasm: support calling alias'd function pointers
When lowering a decl value we verify whether its owner decl index
equals to the decl index of the decl being lowered. When this is not
the case, we are lowering an alias. So instead, we will now lower
the owner decl instead and call its symbol to ensure its type
is being correctly generated.2 files changed, 12 insertions(+), 5 deletions(-)
