Jordan Rose fac5659813 [serialization] Sprinkle PrettyStackTrace throughout deserialization code. ...

Since we don't have soft-failure yet from deserialization, it's helpful to
at least know where to start looking when something crashes. There are some
rough edges here but it should be much better than nothing.

This also pulls the list of record nodes out into a separate file, so that
we can avoid repeating it.

Example crash:
1.	While reading from ./CTypes.swiftmodule
2.	While deserializing 'CBool' (StructDecl)
3.	While deserializing decl #26 (XREF)
4.	Cross-reference to 'LogicValue' in swift
(don't worry, this is an example where I'm tweaking things)
