Original commit message:
[class] handle existing readonly properties in StoreOwnIC
Previously, StoreOwnIC incorrectly reuses the [[Set]] semantics
when initializing public literal class fields and object literals in
certain cases (e.g. when there's no feedback).
This was less of an issue for object literals, but with public class
fields it's possible to define property attributes while the
instance is still being initialized, or to encounter existing static
"name" or "length" properties that should be readonly. This patch
fixes it by
1) Emitting code that calls into the slow stub when
handling StoreOwnIC with existing read-only properties.
2) Adding extra steps in StoreIC::Store to handle such stores
properly with [[DefineOwnProperty]] semantics.
