The infrastructure in semantics that is used to check that the left-hand sides of normal assignment statements are really definable variables was not being used to check whether the LHSs of pointer assignments are modifiable, and so most cases of unmodifiable pointers are left undiagnosed. Rework the semantics checking for pointer assignments, NULLIFY statements, pointer dummy arguments, &c. so that cases of unmodifiable pointers are properly caught. This has been done by extracting all the various definability checking code that has been implemented for different contexts in Fortran into one new facility. The new consolidated definability checking code returns messages meant to be attached as "because: " explanations to context-dependent errors like "left-hand side of assignment is not definable". These new error message texts and their attached explanations affect many existing tests, which have been updated. The testing infrastructure was extended by another patch to properly compare warnings and explanatory messages, which had been ignored until recently.
