We really should set *status to memory_alloc_failure, but we need to refactor
the demangler a bit to properly propagate the failure up the stack. Until then,
its better to explicitly terminate then rely on a null dereference crash.

These are all methods that, while not currently used in the
Itanium demangler, are generally useful enough that it's
likely the itanium demangler could find a use for them. More
importantly, they are all necessary for the Microsoft demangler
which is up and coming in a subsequent patch. Rather than
combine these into a single monolithic patch, I think it makes
sense to commit this utility code first since it is very simple,
this way it won't detract from the substance of the MS demangler
patch.

In a followup I'm looking to add a Microsoft demangler. Doing
so needs a lot of the same utility classes and feature test
macros which are already implemented in ItaniumDemangle.cpp.
So move all of these things into header files so that they
can be re-used by a new demangler.
