Implicits#viewExists: return false after typer instead of AssertionError
This way, tpd#applyOverloaded can safely be used after typer. This issue
was encoutered while working on value classes, step 3 of SIP-15 contains
the following peephole optimization:
new C(e) == new C(f) => e == f
Which requires us to do overloading resolution.
