Simplify RAV isSameMethod with constexpr if
Owing to the large number of instantiations of this function, this small
change has a small but meaningful difference on the total size of
(especially a debug) build of clang at -O0:
```

```
If anyone's got other ideas for how to reduce this further - it's not
especially important, I just came across it while investigating a debug
info size regression, but thought it was interesting enough to poke
around at.
