SI-8450 no "implicit numeric widening" in silent mode
Before this fix, we get a second, spurious warning.
```
t8450.scala:5: warning: implicit numeric widening
def elapsed: Foo = (System.nanoTime - 100L).foo
^
t8450.scala:11: warning: implicit numeric widening
def elapsed: Foo = (System.nanoTime - 100L).foo
^
error: No warnings can be incurred under -Xfatal-warnings.
two warnings found
one error found
```
By respecting silent contexts, we now get only one.
I sneakily fixed similar occurrences without adding a test.
