annotate sema/Symbol.d @ 135:9869194de9b7
Removed some output
We have 15 tests that fail in release mode and 17 in debug - both from things
that are only handled by an assert.
One is a comments lexing test, that fails on an invalid location in debug
The other is returning a struct - it's cought in codegen by an assert, but
should be checked explicitly before that
