Auto merge of #60262 - michaelwoerister:pgo-preinlining-pass, r=alexcrichton

 PGO: Add a run-make test that makes sure that PGO profiling data is used by the compiler during optimizations.

From the tests comment section:
```
# This test makes sure that PGO profiling data leads to cold functions being
# marked as `cold` and hot functions with `inlinehint`.
# The test program contains an `if` were actual execution only ever takes the
# `else` branch. Accordingly, we expect the function that is never called to
# be marked as cold.
```
