8152312: ParNew: Restore preserved marks in parallel

[Tony Printezis]

Hi all,

I was advised to get the ParNew changes reviewed separately from the G1 changes (see 8151556). Here are just the PreservedMarks* changes + the ParNew change:

http://cr.openjdk.java.net/~tonyp/8152312/webrev.0/		

I’ll redo the G1 changes for 8151556 to depend on this change.

I also piggy-backed the following change (for DefNew):

log_debug(gc)("Promotion failed”);
->
log_info(gc, promotion)("Promotion failed”);

so that it’s consistent with what ParNew does. Any objections?

Tony
