6f5cffbc - Mangling: add support for mangling the body-function of asyncHandlers

Mangling: add support for mangling the body-function of asyncHandlers We don't introduce a new mangling here. To distinguish the names of the original asyncHandler function and it's generated "body-function", we just mangle the body-function with an async attribute, i.e. as if it was declared as async. This change is mostly to pass information to the ASTMangler to mangle a not async function as "async".
