Rollup merge of #57677 - dotdash:locals, r=michaelwoerister

const_eval: Predetermine the layout of all locals when pushing a stack frame

Usually the layout of any locals is required at least three times, once
when it becomes live, once when it is written to, and once it is read
from. By adding a cache for them, we can reduce the number of layout
queries speeding up code that is heavy on const_eval.
Empowering everyone to build reliable and efficient software.
