When mangling an APSInt with the ms abi, make sure to look at all nibbles.

Currently, it's ignored if the number of set bits isn't divisible by 4.

While I'm here, resync a %select with the enum definition it selects on.
...
* nullptr used to be mapped to ERROR, now mapped to nullptr
* integral was missing
* expressions now have their own error message, so they won't reach
this. Map them to ERROR.
Note that clang usually crashes before emitting this diagnostic anyway
(see PR13984), so this change alone doesn't have an observable effect.
It makes the code more correct though.

Move expression mangling in the microsoft mangler to its own function.

This matches what's done in ItaniumMangle and makes it a bit easier
to implement mangling for more expressions. Also use the slightly nicer
"not yet implemented" error message from there.
No functionality change (except for the different error message).

Plug a long standing memory leak in TemplateArgument.
...
The integral APSInt value is now stored in a decomposed form and the backing
store for large values is allocated via the ASTContext. This way its not
leaked as TemplateArguments are never destructed when they are allocated in
the ASTContext. Since the integral data is immutable it is now shared between
instances, making copying TemplateArguments a trivial operation.
Currently getting the integral data out of a TemplateArgument requires creating
a new APSInt object. This is cheap when the value is small but can be expensive
if it's not. If this turns out to be an issue a more efficient accessor could
be added.

The idea is that you can create a VarDecl with an unknown type, or a

access that object as long as you explicitly cast it at every use. I'm

I wanted to go ahead and provide a skeletal implementation for the LLDB
folks' benefit and because it also improves some diagnostic goodness for
placeholder expressions.
