Skip or adapt some tests that cannot run DOM-first with upstream fixes

The parser used to build AST isn't recovering as well as the selection
parser. Let's disable those at the moment. They can be re-enabled is the parser
used by ASTParser is made to recover better.
Some other tests related to particular bugs in JDT are also skipped for the moment.

We can't leverage Assume.assume... and skipped tests because those tests
run with JUnit 3
