It would be really neat if there was an option to dump the AST and HIR representations of programs alongside the option to dump the MIR representation. This would be invaluable when working on the compiler.

Note: I think the command to use for printing the HIR would be either -Z unpretty=hir (a source-like representation) or -Z unpretty=hir-tree (more like Debug output).

Note that pretty-printing the AST will probably have to wait until @LeSeulArtichaut implements -Z unpretty=ast.
