Three quick fixes to UStringImpl.

• The destroy() method can be switched back to a normal destructor; since we've switched the way we protect static strings to be using an odd ref-count the destroy() won't abort.
• The cost() calculation logic was wrong. If you have multiple JSStrings wrapping substrings of a base string, they would each report the full cost of the base string to the heap. Instead we should only be reporting once for the base string.
• Remove the overloaded new operator calling fastMalloc, replace this with a 'using' to pick up the implementation from the parent class.

• JavaScriptCore.exp:
• runtime/UStringImpl.cpp:

(JSC::UStringImpl::~UStringImpl):

• runtime/UStringImpl.h:

(JSC::UStringImpl::cost):
(JSC::UStringImpl::deref):
