* Parse (and mostly support) template tag constraints A bunch of tests hit the asserts I added though. * Messy version is finished. Need to add a few tests * Refactor to be smaller * Small refactor + Add one test * Another test * Minor cleanup * Fix error reporting on type parameters on ctors * Simplify syntax of `@template` tag This is a breaking change, but in my sample, nobody except webpack used the erroneous syntax. I need to improve the error message, so jsdocTemplateTag3 currently fails to remind me of that. * Better error message for template tag * Fix fourslash baselines * Another fourslash update * Address PR comments * Simplify getEffectiveTypeParameterDeclarations Make checkGrammarConstructorTypeParameters do a little more work
