verifier. We get most of this infrastructure directly from LLVM, we just
need to adapt it to our CFG abstraction.
This has a few unrelated changes engangled in it:
- getFunction() in various classes was const incorrect, fix it.
- This moves Verifier.cpp to the analysis library, since Verifier depends on
dominance and these are both really analyses.
- IndexedAccessorIterator::reference was defined wrong, leading to really
exciting template errors that were fun to diagnose.
- This flips the boolean sense of the foldOperation() function in constant
folding pass in response to previous patch feedback.

This revamps implementation of the loop bounds in the ForStmt, using general representation that supports operands. The frequent case of constant bounds is supported
via special access methods.
This also includes:
- Operand iterators for the Statement class.
- OpPointer::is() method to query the class of the Operation.
- Support for the bound shorthand notation parsing and printing.
- Validity checks for the bound operands used as dim ids and symbols
I didn't mean this CL to be so large. It just happened this way, as one thing led to another.

generalize the asmprinters handling of pretty names to allow arbitrary sugar to
be dumped on various constructs. Give CFG function arguments nice "arg0" names
like MLFunctions get, and give constant integers pretty names like %c37 for a
constant 377
