Simplify date conversion functions

Do not use the 3rd-party code from JSC, but instead use the QDateTime
functions for millisecond offsets from the epoch.

Note that this change is reviving the earlier change:
http://codereview.qt-project.org/1874.  The test failures for that
change no longer occur due to a change in the QDateTime behavior
applied by: http://codereview.qt-project.org/13169

There is still a semantic difference between QDateTime and the
ECMAScript specification with regards to the application of DST.
ECMAScript requires that the current DST adjustment should be applied
to historical dates, whereas QDateTime will apply the adjustment as
applicable at the epoch date to any prior dates.

Create accessible interfaces only for items with attached prop

On the other hand this patch enables the root item to be found

the hierarchy is not valid again.

Fix constant folding for simple binary expression

Also, we go back generating quadruples instead of
IR-tree-expressions. This is kind of needed to reduce register
pressure in the V4 VM. That is, V4 has typed registers so before
reusing a register we need to look at the type and eventually
dispose its contents (e.g. when a QString or a QUrl is stored
in the register). Unfortunately, we can't effort to have all
these checks in the V4 instructions. So we change `binop'
to generate literals (e.g. CONST or STRING) or a TEMP (aka
a preassigned register that cannot be reused).
