Semantic analysis was emitting a bogus error message when a structure constructor contains a monomorphic value for a (limited) polymorphic component of a derived type. The type compatibility test was too strict; this patch relaxes it a little to allow values that could be assigned or passed to a variable or dummy argument with that type. Also add some quotes to an error message that was sometimes confusing without them, and remove a repeated space character from another. Differential Revision: https://reviews.llvm.org/D119744
