Reduce page cache size on Mac
https://bugs.webkit.org/show_bug.cgi?id=111795
Rubber stamped by Geoff Garen
5 entries is unnecessarily large; research show 3 should suffice.
On a low memory warning we should clear this completely.
Source/WebCore:
* platform/mac/MemoryPressureHandlerMac.mm:
(WebCore::MemoryPressureHandler::releaseMemory):
- clear the page cache completely
Source/WebKit2:
* Shared/CacheModel.cpp:
(WebKit::calculateCacheSizes):
- reduce maximum to 3.
