Don't crash in llvm-pdbutil when dumping TypeIndexes with high bit set.

This is a special code that indicates that it's a function id.
While I'm still not certain how to interpret these, we definitely
should *not* be using these values as indices into an array directly.
For now, when we encounter one of these, just print the numeric value.
