Fix bug of accidentally overriding initial layout location with 0, which does not mean no location.  Added in/out structure tests.

Track separate precision defaults for each kind of sampler, give initial defaults as per spec. Also make fragment floats have no default.  Modify/add tests to adapt to these changes.

Simply compile-time error handling: mostly removed the need to test an error occurred and the need to call recover().

Block/structure fixes: Merge qualifiers with multiple declarators, handle arrays of blocks, more semantic checks for what's allowed.

A bunch of semantic checks were missing for binary arithmetic operations. Refactor the "promote" logic to fix these.

Make the PP report an error on undefined macro in "#if ..." for ES profiles, unless relaxed error checking is requested.  Still works as normal CPP on non-ES.

Also, improved error reporting in general for the PP.
