Implementing -print-before-all/-print-after-all/-filter-print-func support
through PassInstrumentation callbacks.
- PrintIR routines implement printing callbacks.
- StandardInstrumentations class provides a central place to manage all
the "standard" in-tree pass instrumentations. Currently it registers
PrintIR callbacks.

Summary:
Adding support for -print-module-scope similar to how it is
being done for function passes. This option causes loop-pass printer
to emit a whole-module IR instead of just a loop itself.

Summary:
Loop-pass printing is somewhat deficient since it does not provide the
context around the loop (e.g. preheader). This context information becomes
pretty essential when analyzing transformations that move stuff out of the loop.
Extending printLoop to cover preheader and exit blocks (if any).
