Chris Lattner 80b6bd24b3 Implement parser/IR support for CFG functions, basic blocks and return instruction. 
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.

Chris Lattner 49795d166f Introduce IR support for MLIRContext, primitive types, function types, and 
vector types.

tensors and memref types are still TODO, and would be a good starter project
for someone.

Chris Lattner 23b784a1bb Implement parser and lexer support for most of the type grammar. 
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.

Chris Lattner 9b9f7ff5d4 Implement enough of a lexer and parser for MLIR to parse extfunc's without 
arguments.
