Support caching of custom setters
​https://bugs.webkit.org/show_bug.cgi?id=129519

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

This patch adds caching of assignment to properties that
are backed by C functions. This provides most of the leg
work required to start supporting setters, and resolves
the remaining regressions from moving DOM properties up
the prototype chain.
