2025-06-24	Tweak `-Zmacro-stats` measurement.	Nicholas Nethercote	-18/+10
	It currently reports net size, i.e. size(output) - size(input). After some use I think this is sub-optimal, and it's better to just report size(output). Because for derive macros the input size is always 1, and for attribute macros it's almost always 1.
2025-06-12	Introduce `-Zmacro-stats`.	Nicholas Nethercote	-0/+171
	It collects data about macro expansions and prints them in a table after expansion finishes. It's very useful for detecting macro bloat, especially for proc macros. Details: - It measures code snippets by pretty-printing them and then measuring lines and bytes. This required a bunch of additional pretty-printing plumbing, in `rustc_ast_pretty` and `rustc_expand`. - The measurement is done in `MacroExpander::expand_invoc`. - The measurements are stored in `ExtCtxt::macro_stats`.
