Subject: Dump results of analysis phase as CSV

Adds the option -Zsave-analysis which will dump the results of syntax and type checking into CSV files. These can be interpreted by tools such as DXR to provide semantic information about Rust programs for code search, cross-reference, etc.

Authored by Nick Cameron and Peter Elmers (@pelmers; including enums, type parameters/generics).
