www/firefox: apply upstream powerpc64 fixes

Many of these are stalled on review for various reasons but the intent of each seems clear enough to keep rebasing or ask upstream for help. pkg-fallout@ would identify rebase mistakes while atomic changes would identify when a particular patch is no longer useful. Submitted by: mikael (via D21765)

+Problem description: Tab-titles that are too long to fit into a tab get faded out.
+                     On big endian this is broken and instead of fading out, the 
+                     tab gets white and the font transparent, leading to an unreadable
+                     tab-title
+Solution: This is not a real solution, but a hack. The real solution would have been
+          to byte-swap the correct buffer, but I could not find it.
+          So the next best thing is to deactivate the fading-effect. Now all tab-titles
+          are readable, albeit not as pretty to look at as they could be. 
+Side-effects: I have not yet found an unwanted side-effect.

+For FF68, AntiAliasing of XULTexts seem to be broken on big endian (s390x). Text and icons of the sandwich-menu to the
+right of the address bar, as well as plugin-windows appears transparant, which usually means unreadable (white on white).
