move test files that fail spuriously to pending

I have this sneaky suspicion that part of these spurious failures
are caused by the recent partest optimizations.

@axel22 already checked that compiler instances are not shared between test runs.
However, except for the benchmark test, they all have a distinct
race condition in symbol loading/type checking feel to them.

Since, in the end, the tests and/or their corresponding fixes are as likely
a culprit as the test framework, moving them out of the way until their owners
can get them back in line and they stop throwing primate wenches into our build.

We should bring them back as soon as possible, though.
