  1. 8350621 

    Hi all,

  please review this change to avoid CodeCache triggered GCs temporarily being ignored.

In particular, G1 does not make sure when its `collect()` method is called during a
concurrent cycle, that a `Remark` pause that does code unloading etc. actually occurs
after that request. This makes it so that some internal flag is not reset appropriately,
stuck until the next code unloading (caused by e.g. a regular concurrent cycle being
triggered).

Testing: tier1-5

Thanks,
  Thomas
