a358be0ef7 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.

711c726c97 Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces. 
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

a9985913d7 It's not necessary for PrintModulePass to flush the output streams 
now that errs() is properly non-buffered.

919ce3c16a Privatize PrintModulePass and PrintFunctionPass and add 
createPrintModulePass and createPrintFunctionPass.
 - So clients who compile w/o RTTI can use them.
