Move some methods from tcx.hir() to tcx

zetanumbers · zetanumbers · commit fe37cc1d9783 · 2023-12-12T06:40:29.000-08:00
Renamings:
- find -&gt; opt_hir_node
- get -&gt; hir_node
- find_by_def_id -&gt; opt_hir_node_by_def_id
- get_by_def_id -&gt; hir_node_by_def_id

Fix rebase changes using removed methods

Use `tcx.hir_node_by_def_id()` whenever possible in compiler

Fix clippy errors

Fix compiler

Apply suggestions from code review

Co-authored-by: Vadim Petrochenkov &lt;vadim.petrochenkov@gmail.com&gt;

Add FIXME for `tcx.hir()` returned type about its removal

Simplify with with `tcx.hir_node_by_def_id`
