Add additional regression tests for PGO

This PR adds regression tests for making sure that
- instrumentation records the right counts for branches taken and functions called, and that
- the indirect call promotion pass actually is able to promote indirect calls.

0f6f66fcdc Auto merge of #66561 - TimoFreiberg:trait-name-report, r=estebank 
Add version mismatch help message for unimplemented trait

Improves issue #22750

The error reporting for E0277 (the trait `X` is not implemented for `Foo`)
now checks whether `Foo` implements a trait with the same path as `X`,
which probably means that the programmer wanted to actually use only one
version of the trait `X` instead of the two.

Still open:
* the same diagnostic should be added for [the trait method case](https://github.com/rust-lang/rust/issues/22750#issuecomment-372077056)
* Showing the real crate versions would be nice, but rustc currently doesn't have that information [according to Esteban](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/diagnostics.20for.20crate.20version.20mismatch/near/180572989)

483a83b6e6 Auto merge of #66178 - Aaron1011:fix/opaque-normalize, r=varkor 
Fix opaque types resulting from projections in function signature

When we normalize the types in a function signature, we may end up
resolving a projection to an opaque type (e.g. `Self::MyType` when
we have `type MyType = impl SomeTrait`). When the projection is
resolved, we will instantiate the generic parameters into fresh
inference variables.

While we do want to normalize projections to opaque types, we don't want
to replace the explicit generic parameters (e.g. `T` in `impl
MyTrait<T>`) with inference variables. We want the opaque type in the
function signature to be eligible to be a defining use of that opaque
type - adding inference variables prevents this, since the opaque type
substs now appears to refer to some specific type, rather than a generic
type.

To resolve this issue, we inspect the opaque types in the function
signature after normalization. Any inference variables in the substs are
replaced with the corresponding generic parameter in the identity substs
(e.g. `T` in `impl MyTrait<T>`). Note that normalization is the only way
that we can end up with inference variables in opaque substs in a
function signature - users have no way of getting inference variables
into a function signature.

Note that all of this refers to the opaque type (ty::Opaque) and its
subst - *not* to the underlying type.

Fixes #59342
