- introduce affine integer sets into the IR
- parse and print affine integer sets (both inline or outlined) similar to
affine maps
- use integer set for IfStmt's conditional, and implement parsing of IfStmt's
conditional
- fixed an affine expr paren omission bug while one this.
TODO: parse/represent/print MLValue operands to affine integer set references.

- Implement a diagnostic hook in one of the paths in mlir-opt which
captures and reports the diagnostics nicely.
- Have the parser capture simple location information from the parser
indicating where each op came from in the source .mlir file.
- Add a verifyDominance() method to MLFuncVerifier to demo this, resolving b/112086163
- Add some PrettyStackTrace handlers to make crashes in the testsuite easier
to track down.

Fix b/112039912 - we were recording 'i' instead of '%i' for loop induction variables causing "use of undefined SSA value" error.

Induction variables are implemented by inheriting ForStmt from MLValue. ForStmt provides APIs that make this design decision invisible to the ForStmt users.
This CL in combination with cl/206253643 resolves http://b/111769060.

and OtherType. Other type is now the thing that holds AffineInt, Control,
eventually Resource, Variant, String, etc. FloatType holds the floating point
types, and allows convenient query of isa<FloatType>().
This fixes issues where we allowed control to be the element type of tensor,
memref, vector. At the same time, ban AffineInt from being an element of a
vector/memref/tensor as well since we don't need it.
I updated the spec to match this as well.

- Enhance memref type to allow omission of mappings and address
spaces (implying a default mapping).
- Fix printing of function types to properly recurse with printType
so mappings are printed by name.
- Simplify parsing of AffineMaps a bit now that we have
isSymbolicOrConstant()

This regresses parser error recovery in some cases (in invalid.mlir) which I'll
consider in a follow-up patch. The important thing in this patch is that the
parse methods in StandardOps.cpp are nice and simple.

This looks heavyweight but most of the code is in the massive number of operand accessors!
We need to be able to iterate over all operands to the condbr (all live-outs) but also just
the true/just the false operands too.
