9265197c4e Implement initial support for function attributes, including parser, printer,
resolver support.

Still TODO are verifier support (to make sure you don't use an attribute for a
function in another module) and the TODO in ModuleParser::finalizeModule that I
will handle in the next patch.

ae79d69922 Implement a module-level symbol table for functions, enforcing uniqueness of
names across the module and auto-renaming conflicts.  Have the parser reject
malformed modules that have redefinitions.

prone to create things.

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.

5fc587ecf8 Continue sketching out basic infrastructure, including an input and output
filename, and printing of trivial stuff.  There is no parser yet, so the
input file is ignored.
