Masayuki Nakano 6b9eda1dda Bug 1392181 - part2: HasRTLChars() should check if the character is at least equal or larger than the minimum RTL character, U+0590 r=emk
HasRTLChars() appears in profile of attachment 8848015 after landing the patches
for bug 1391538 because the landing made text in <input> or <textarea> always
treated as non-single byte characters.  Therefore, HasRTLChars() is now called
by nsTextFragment::SetTo() a lot in editors.

HasRTLChar() checks if it's in an RTL character for each character until it
becomes true.  However, if character is less than the minimum RTL character,
U+0590, it works faster at least for Western languages.
