test symboo.defTree for symbols from Tasty

@liufengyun liufengyun requested a review from abgruszecki August 21, 2019 12:58
@liufengyun liufengyun force-pushed the test-defTree branch 5 times, most recently from d6e6080 to 10c6316 Compare August 24, 2019 08:39
The scripted tests only run every night
This needs to be changed because `Pickler` does not exists for running staged code.
As the compiler supports already adding custom phases,
there is no need to add the phases to the compiler.
The following invariant should be true for pattern-bound symbols,
and *only* for pattern-bound symbols:

    (sym.isType && !sym.isClass && sym.isOneOf(Case)) ||
      (sym.isTerm && sym.isOneOf(Case, butNot = Enum | Module))

The invariant only holds before patternMatcher.
After patternMatcher, there are no more pattern trees,
thus the invariant does not hold any more.
Those symbols are now normal ValDefs, thus should not have
the Case flag.
