Updated the install location for EnhancedDisassembly
on Mac OS X to use @rpath rather than an absolute
path.  Also allowed the version to be set using an
environment variable.

Check for terminating conditions before adding PHIs to the worklists.
This is more efficient than adding them to the worklist and then ignoring them.

David Greene [Thu, 1 Apr 2010 22:43:57 +0000 (22:43 +0000)]
Add some switches helpful for debugging:

-print-before=<Pass Name>

Dump IR before running pass <Pass Name>.

-print-before-all

Dump IR before running each pass.

-print-after-all

Dump IR after running each pass.

These are helpful when tracking down a miscompilation.  It is easy to
get IR dumps and do diffs on them, etc.

To make this work well, add a new getPrinterPass API to Pass so that
each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
suitable for dumping out the kind of object the Pass works on.
