[PATCH] D50631: [AST] Stuff more data into FunctionTypeBitfields

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

We should absolutely have static assertions to check that these bit-field types don't get larger than 32 bits.  A lot of the subclass layouts have been tweaked to fit that (packing into the tail padding of `Type` on 64-bit targets), so accidentally overflowing to use more bits in the base is going to lead to a lot of bloat.
