Sema: Properly support Microsoft-mode template arguments
Summary:
There were two things known to be wrong with our implementation of MSVC
mode template arguments:
- We didn't properly handle __uuidof/CXXUuidofExpr and skipped all type
checking completely.
- We didn't allow for MSVC's extension of allowing certain constant
"foldable" expressions from showing up in template arguments.
They allow various casts dereference and address-of operations.
We can make it more general as we find further peculiarities but this
is the known extent.
