Auto merge of #43844 - arielb1:literally-nonstandard, r=eddyb
ast_validation: forbid "nonstandard" literal patterns Since #42886, macros can create "nonstandard" PatKind::Lit patterns, that contain path expressions instead of the usual literal expr. These can cause trouble, including ICEs. We *could* map these nonstandard patterns to PatKind::Path patterns during HIR lowering, but that would be much effort for little gain, and I think is too risky for beta. So let's just forbid them during AST validation. Fixes #43250. beta-nominating because regression. r? @eddyb
