Update and tests for %RegExpPrototype% methods

A recent web-compatability change to ECMA262 modified the semantics of
the accessor methods on the %RegExpPrototype% intrinsic--the "get"
accessors now include steps dedicated to the case where the "this" value
is the %RegExpPrototype% object itself.

Remove the tests that have been invalidated by this change, introduce
tests asserting the new behavior, and extend coverage for other possible
"this" values.
