Remove getCallDataVirtual methods
​https://bugs.webkit.org/show_bug.cgi?id=69186

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Removed all getCallDataVirtual methods and replaced their call sites
with an explicit lookup in the MethodTable.

To allow subclasses of InternalFunction (e.g. QtRuntimeMethod) to not have
to declare their own ClassInfo if they don't override getCallData, provided
an implementation that calls ASSERT_NOT_REACHED if called, providing roughly the same
functionality as of the pure virtual method InternalFunction used to have.
Also made this new implementation protected rather than private for the same reason.
Also added an ASSERT in InternalFunction::finishCreation to make sure that whatever
object is being created provides their own implementation of getCallData. This
just makes execution fail earlier in a place where the source of the error is
easy to trace. These ASSERTs are better than putting a null in the MethodTable because
they appear much more intentional to anybody who fails to provide their own
implementation or who tries to explicitly call InternalFunction::getCallData.

Added a global structure to JSGlobalObject for StrictModeTypeErrorFunction to enable
it to be reused rather than creating a new Structure every time we instantiate it.
