Shu-yu Guo 15cc02b4e8 [shared-struct] Disallow property redefinition
Shared objects have fixed layout (i.e. immutable maps) and start off
sealed. Ordinary JS objects allow writable properties to be redefined to
be non-writable. This violates the fixed layout invariant and needs to
be disallowed.

Also contains a drive-by fix removing
@highestInstanceTypeWithinParentClassRange, which is unneeded.
