I am thinking on doing this some other way.
Copying the PrintingPolicy object is very expensive, as it contains quite a few
strings and vectors of strings.
In the past I changed this matcher to make no allocations in the common path
(ie using SmallString<>, etc) to reduce its cost.
Adding that copy will make it expensive again.
Also, this change is not completely correct. It either uses all namespaces or
none of the inline.
It won't partially match.
Eg:
namespace A {
inline namespace B {
inline namespace C {
void F();
}
}
}
We should be able to match `F` as `A::C::F` and that doesn't work right now.

Thanks. I assumed it worked because we already allow range-for in LLVM.
Extracted the array into a variable.

Which braces do you want to remove?
I need these to make the else bind with the outer if().
Applied clang-format.
