WebCore:

The timeout is caused by 59659 that changed the GC timer to 0 and thus
triggered a bug in FileReader code. The fix is to add more states so
that hasPendingActivity() can do the check correctly.

* html/FileReader.cpp:
(WebCore::FileReader::FileReader):
(WebCore::FileReader::hasPendingActivity):
(WebCore::FileReader::readInternal):
(WebCore::FileReader::terminate):
(WebCore::FileReader::didStart):
(WebCore::FileReader::didGetSize):
(WebCore::FileReader::didRead):
(WebCore::FileReader::didFinish):
(WebCore::FileReader::didFail):
(WebCore::FileReader::readyState):
(WebCore::FileReader::result):
* html/FileReader.h:
(WebCore::FileReader::):

LayoutTests:

Re-enale the file reader test.
