8b3783e2ea [flang] Fix build problem with clang 
Moving one of the `Pre(ImplicitStmt)` functions up to
`DeclarationVisitor` seemed to cause clang to complain that the `Pre`
call from the `Walk` function was ambiguous. So this change moves
it back to `ResolveNameVisitor`.

Also, remove an unused variable that was causing a warning.

b6eb981caa [flang] Handle SAVE attribute and statement 
As with COMMON blocks, we can't completely check SAVE statements and
attributes until the end of the specification part when we have seen
full declarations of entities. So when SAVE is specified, add it to one
of the two sets in `saveInfo_`. At the end of the specification part,
check that those entities can have SAVE applied and set it if it is
not already implicitly set (e.g. due to being in a module). Also apply
the "global" SAVE if present (i.e. setting it on every applicable
entity).

Add `IsDummy()` and `IsFuncResult()` to `Symbol` to simplify some of
the checks. Also detect attempts to put a function result in a common
block.

efd7bdb030 [flang] Remove TODO for saved-entity 
The parser can't distinguish `saved-entity -> object-name` from
`saved-entity -> proc-pointer-name`. So just use `kind` == `Entity`
for those cases. Name resolution will verify it is the right kind
of entity name.

a6874f8ee8 [flang] More work on COMMON blocks 
Common block names can't clash with other names, so add `commonBlocks_`
to `Scope` to record the common blocks of a scoping unit. This requires
changes to how scopes are dumped and written to `.mod` files.

Support common blocks in BIND statements. Add optional bind-name to
`CommonBlockDetails`.

Add `CheckNotInBlock()` for checking statements that are not allowed in
block constructs.

In `rewrite-parse-tree.cc`, no longer skip check for resolved names in
common statements. But do skip the checks in compiler directives.

8a03a67cb0 [flang] Change handling of BIND attributes 
Previously `BIND(C, NAME="...")` caused `bindName` to be set but not
the `BIND` attribute. This made writing the `.mod` file easier, but it
makes it hard to ask: does this symbol have a C binding.

This change causes the `BIND` attribute to be set whenever there is
`BIND(C)` in the source, regardless of whether there is a name or not.
`bindName` is only set when the `BIND` attribute is also set.
