This CL adds the start of an architecture document which can be expanded
as needed. The document is mostly an architecture diagram of how the
various pieces fit together.

This Cl fixes the function parsing so the opening brace is required.
This will return an error now. The statement::body_stmt is changed to
make the open paren optional.

This CL removes the complete coverage of the possible input formats
infavor of simpler testing of a few of the inputs. This should be
sufficient coverage and makes the tests easier to read.
The incorrect OpConstantNull for the samplers and textures has also been
removed.

This CL removes the instantiated test suites, instead it tests each of
the required formats with one texture type and then uses the rest of the
tests to verify the texture type generated is correct.
This makes the tests a lot easier to read as the string generation for
results is removed.

Currently if the type determiner is determining an identifier it will
wrap it into a pointer if it isn't a constant. This CL updates to make
sure we don't already have a pointer as otherwise we endup with a double
pointer.
