needs to be, but I couldn't find something simpler that dealt with all of the
corner cases.

$T8 shows up as register $24 when emitted from C++ code so we had
to change some tests that were already there for this functionality.

control the visibility of a type for the purposes of RTTI
and template argument restrictions independently of how
visibility propagates to its non-type member declarations.

Also fix r175326 to not ignore template argument visibility
on a template explicit instantiation when a member has
an explicit attribute but the instantiation does not.

for the data specific to a macro definition (e.g. what the tokens are), and
MacroDirective class which encapsulates the changes to the "macro namespace"
(e.g. the location where the macro name became active, the location where it was undefined, etc.)

(A MacroDirective always points to a MacroInfo object.)

Usually a macro definition (MacroInfo) is where a macro name becomes active (MacroDirective) but
splitting the concepts allows us to better model the effect of modules to the macro namespace
(also as a bonus it allows better modeling of push_macro/pop_macro #pragmas).
Modules can have their own macro history, separate from the local (current translation unit)
macro history; MacroDirectives will be used to model the macro history (changes to macro namespace).

For example, if "@import A;" imports macro FOO, there will be a new local MacroDirective created
to indicate that "FOO" became active at the import location. Module "A" itself will contain another
MacroDirective in its macro history (at the point of the definition of FOO) and both MacroDirectives
will point to the same MacroInfo object.

Introducing the separation of macro concepts is the first part towards better modeling of module macros.

RegionStoreManager::getInterestingValues() returns a pointer to a
std::vector that lives inside a DenseMap, which is constructed on demand.
However, constructing one such value can lead to constructing another
value, which will invalidate the reference created earlier.

Fixed by delaying the new entry creation until the function returns.

This generalizes Optional to require less from the T type by using aligned
storage for backing & placement new/deleting the T into it when necessary.

Add the function attributes from an inline asm call. These don't have declarations that set the attribute groups, so we must do it on our own.

MS-style inline assembly.

This is a follow-on to r175334.  Forcing a FP to be emitted doesn't ensure it
will be used.  Therefore, force the base pointer as well.  We now treat MS
inline assembly in the same way we treat functions with dynamic stack
realignment and VLAs.  This guarantees the BP will be used to reference 
parameters and locals.

fixit for attributes-in-the-wrong-place code and reuse it here, if attributes
are placed after the access-specifier or 'virtual' in a base specifier.

Be more user-friendly about not having scripting enabled:
a) if Python was built-out then tell people about it explicitly
b) if we are told to use none as a scripting language, then tell people about that too

This should limit the cases where the semi-cryptic error message "there is no embedded script interpreter in this mode." actually shows
