Fergus Henderson 36bb97d223 Fix a bug where the compiler was silently accepting invalid code. ...

Estimated hours taken: 6
Branches: main, release

Fix a bug where the compiler was silently accepting invalid code.

doc/reference_manual.texi:
	Document that type class methods must have their modes and
	determinism explicitly declared.

compiler/make_hlds.m:
	Report errors for predicate type class methods with no modes
	or with modes but no determinism.

compiler/check_typeclass.m:
compiler/polymorphism.m:
	Handle the case where a method has no declared determinism:
	since make_hlds.m will have already reported the error,
	we just need to avoid aborting or issuing spurious flow-on errors.

	Update the expected output for this existing test.
