Implement USE statements.

9727b06813 [flang] Support for USE statements. 
When a USE statement is encountered, find the scope corresponding to the
module. This is now stored in the ModuleDetails of the module symbol.
useModuleScope_ tracks this while processing the USE. Currently only
modules defined in the same file work because we don't have module files.

At the end of a USE that isn't a use-only, add all public names that
were not renamed.

AddUse() handles recording of a USE by creating a local symbol with
UseDetails that tracks the use-symbol in the module and the location of
the USE (for error messages). If an ambiguous USE is detected, the
UseDetails are replaced by UseErrorDetails. This tracks the locations of
all the uses so that they can be referenced in a diagnostic.

Detect attempts to re-declare use-associated symbols as well as changing
their attributes (except for ASYNCHRONOUS and VOLATILE).

Add missing checks for access-stmt in scoping units other than modules.

Add tests for the new errors.

Reorganize the MessageHandler::Say() overloadings to prevent them from
becoming too numerous.

be1a9990a8 [flang] resolve-names.cc reorganization and cleanup. 
Add ScopeHandle class to manage the stack of scopes and MakeSymbol(), which
makes a symbol in the current scope. Move the call to ApplyImplicitScopes()
into PopScope() as it must be done for each scope.

Add ModuleVisitor class to manage module-related resolution. Currently that
consists of beginning and ending modules and access statements. This is
preparation for further module work.

Replace references to parser::CharBlock with SourceName.
