Tim Keith 2fb1c16e94 [flang] Clean up; fix assert and crashes 
This is the result of running `f18 -fdebug-resolve-names` on a bunch of
Fortran source and fixing the resulting assertion errors and segmentation
faults.

Most of the problems were with encountering attributes, array specs, or
declaration type specs when we weren't prepared to handle them. Those
were fixed by adding calls to {Begin,End}DeclTypeSpec and {Begin,End}Decl
when encountering certain nodes, though the real work for those nodes is
still to be done.

Extract some common functionality into PostAttrSpec and CheckUseError.

Add missing XOR to GenericSpec.

Tim Keith 4c99dc2a94 [flang] Support interface blocks. 
Add subprogram symbols for each interface-body and set isInterface on
them. Create a symbol with GenericDetails for each generic interface
block and add interface specifications to the specific procedures of
the generic. InterfaceVisitor takes care of this.

Before processing the specification part of modules and subprograms,
collect the names of module subprograms and internal subprograms and add
them to the symbol table with SubprogramNameDetails. This allows us to
reference them from interface blocks in the specification part.
SubprogramNameDetails is converted to SubprogramDetails when the real
subprogram is visited.

This is achieved by setting subpNamesOnly_ and then walking the
ModuleSubprogramPart or InternalSubprogramPart. Creating the symbol and
scope for a module or subprogram now happens when the Module,
SubroutineSubprogram, or FunctionSubprogram node is encountered so
this can happen in the right order.

Add BeginSubprogram and EndSubprogram to handle the parts in common
between subprograms and interface specifications.

Add GenericSpec to type.h to represent all possible generic specs.
Only generic names are resolved so far.

Add tests for new error messages. Change resolve02.f90 to reflect the
new errors reported.

Tim Keith 3c1f2b9670 [flang] Extract class SubprogramVisitor out of ResolveNamesVisitor. 
This is just refactoring. SubprogramVisitor now contains the functionality
related to subprograms, including statement functions. This is preparation
for handling interface blocks.

Also, change MessageHandler to create the Messages object and return it
through an accessor rather than having it created outside and passed in.
This saves us from having to pass it up through the chain of constructors.
