Rollup merge of rust-lang#58137 - ljedrz:cleanup_node_id_to_type, r=estebank

Centril · web-flow · commit f6da2895bc58 · 2019-02-13T02:24:13.000+01:00
Cleanup: rename node_id_to_type(_opt) Renames `node_id_to_type(_opt)` to `hir_id_to_type(_opt)`; this makes it clear we are dealing with HIR nodes and their IDs here. In addition, a drive-by commit removing `ty::item_path::hir_path_str` (as requested by @eddyb).
