Fix maxHeapSize update after Full Opportunistic GC
https://bugs.webkit.org/show_bug.cgi?id=295560
rdar://155270113
Reviewed by Yusuke Suzuki.
Before this change, we would not update m_maxHeapSize after Full Opportunistic
GC,
but we would update m_maxEdenSize, resulting in very small or large
m_maxEdenSize
in some cases, which can churn GC or cause Eden GCs to grow the heap too much.
Change this to update m_maxEdenSize normally, but allow eden to become larger
than
m_maxEdenSize up to m_maxHeapSize if the last Full GC was Opportunistic.
