ART: Add capability for a pass to have options

This patch adds capability to have pass options. These are needed when a pass
has multiple flags that can be tweaked. The user is now allowed to pass those
options via command line.

Since passes are treated as singletons and they are immutable, the overridden
options provided by user are set on the compilation unit. Doing this way also
allows a selectivity system to tweak the option per compilation instead of
doing it globally (due to the single pass existing).

The following command line flags have been added:
--print-pass-options - This prints all passes that have options along with
their defaults.
--pass-options= - This is used to pass the overridden options in format of
PassName:PassOption:PassOptionSetting
