[Win32] Start releasing memory earlier when memory is running low.
https://bugs.webkit.org/show_bug.cgi?id=164862
Reviewed by Brent Fulgham.
On Windows, 32-bit processes have 2GB of memory available, where some is used by the system.
Debugging has shown that allocations might fail and cause crashes when memory usage is > ~1GB.
We should start releasing memory before we reach 1GB.
