debuginfo: Simplify TypeMap used during LLVM debuginfo generation.

The previous implementation was written before types were properly normalized for code generation and had to assume a more complicated relationship between types and their debuginfo -- generating separate identifiers for debuginfo nodes that were based on normalized types. Since types are now already normalized, we can use them as identifiers for debuginfo nodes.
