Tim Keith da414d7c3f [flang] Collect implicit type rules and report related errors. ... ImplicitRules maintains a mapping of initial character of an identifier to its implicit type. ImplicitRulesVisitor visits the ImplicitStmt and related parse tree nodes and updates the rules. Emit errors messages in these cases: - implicit type specified more than once for a letter - IMPLICIT statement and IMPLICIT NONE in same scope - IMPLICIT statement and IMPLICIT NONE(TYPE) in same scope - more than one IMPLICIT NONE in a scope - IMPLICIT statement with empty range of letters - IMPLICIT NONE statement after PARAMETER statement - TYPE or EXTERNAL repeated in an IMPLICIT NONE statement Also start emitting error messages through the parser::Messages interface. An instance of Messages is created from the cooked source and saved in the MessageHandler class. It tracks the source location of the current statement and provides a way to emit messages associated with that statement.
