WIP bless example, demoing `minimal` mode accros the tree.

This is incomplete because it does not cover all type errors, and there
may still be some bugs.

Auto merge of rust-lang#27822 - arielb1:inline-round-take-2, r=Gankro

This speeds up rustc on rust-lang#25916 from 1.36±0.022s to 1.326±0.025s

Tests pass locally (even on 32-bit :-)
