Auto merge of #65927 - eddyb:eval-always-considered-harmful, r=michaelwoerister
Don't use eval_always for miri queries used from codegen. This should fix the [massive incremental perf regression](https://perf.rust-lang.org/compare.html?start=95f437b3cfb2fec966d7eaf69d7c2e36f9c274d1&end=9285d401a6070094747465962bc49969b93e14c5&stat=instructions:u) introduced in #65664. It seems that `eval_always` was mistakenly(?) added to `const_field` and then it ended up on `const_caller_location` (which is used much more often than `const_field` is). r? @michaelwoerister cc @oli-obk @nnethercote
