Add diagnostic reporter function to lexer/parser and use that from mlir-opt to report errors instead of having the lexer/parser print the errors.

Add parsing tests with errors. Follows direct path of splitting file into test groups (using a marker) and parsing each section individually. The expected errors are checked using FileCheck and parser error does not result in terminating parsing the rest of the file if check-parser-error.
This is an interim approach until refactoring lexer/parser.

This is pretty much minimal scaffolding for this step. Basic block arguments,
instructions, other terminators, a proper IR representation for
blocks/instructions, etc are all coming.

Semi-affine maps and address spaces are not yet supported (someone want to take
this on?). We also don't generate IR objects for types yet, which I plan to
tackle next.
