cba2e924d6 Bug 1005500 - Use a separate linear scan pass to mark nodes white in ScanRoots. r=smaug 
The existing code for ScanRoots looks at all traversal roots in the graph,
and floods white or black from them. This can take up a large chunk of the
Scan/Unlink slice of ICC, maybe because graph traversal has poor locality.

Outside of a leak, the cycle collector graph is usually only large when
there is a lot of garbage (95% or more of the graph), so we want to
speed up white marking.

To do this, I add a new pass that scans every node and directly sets the
color of any node that should be white, without flooding. This is very
fast. Then a second pass floods black from any remaining grey nodes.

On the page close CC for a real page, I measured a 10x improvement in
ScanRoots() time with this algorithm, from 3ms to 0.3ms.

3b4495d665 Bug 991791 - Fix some timing-dependent edge cases in nsMemoryReporterManager child handling. r=njn 
The patch for bug 946407 changed the state space of
nsMemoryReporterManager in a subtle way: if we're using
MinimizeMemoryUsage with our report, then it's possible for all of
the child processes to finish (or for the timeout to expire) before
the parent has started reporting on itself.  This could cause us to
dereference a null pointer to the state struct in StartGettingReports().

To fix this, we keep track of whether the parent has actually done its
report, and defer finishing the report until then.
