This commit is the result of a general audit of the expression parser to locate instances where dyn_cast<>() and isa<>() are used on types, and replace them with getAs<>() as appropriate. The difference is that dyn_cast<>() and isa<>() are essentially LLVM/Clang's equivalent of RTTI -- that is, they try to downcast the object and return NULL if they cannot -- but getAs<>() can traverse typedefs to perform a semantic cast. llvm-svn: 146537
