Bug 1375833 - Part 1: Do not clear subframe history on normal reload. r=smaug

Browse Source 
In bug 1326251 we made gecko aggressively clear frame history. It turns out to
be too aggressive comparing to all other major browsers. This patch reverses
the behavior, so that only force reload and fresh would clear frame history,
but not normal reload.
