[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.

[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.

[flang] Add support for common blocks

A symbol for a common block has `CommonBlockDetails` which contains
a list of the symbols that are in the common block.

The name of the symbol for the blank common block is the empty string.
That preserves the property that every symbol name is a substring of
the cooked source. We use the 0-length substring starting at the COMMON
statement so that when symbols are sorted by the location of the start
of the name it ends up in the right place.

Some of the checks on members of common blocks don't happen until the
end of the scope. They can't happen earlier because we don't necessarily
know the type and attributes.

Enhance `test_errors.sh` so that multiple errors can be expected for
a single line.

[flang] Simplify CommonStmt in parse tree

The grammar requires parsing the first common block in a common stmt
differently from the others: the '//' is optional for the blank common.

But once it's parsed, it is easier to work with if each is represented
as a `parser::CommonStmt::Block`. This is achieved by using the same
constructor for `CommonStmt` but then including the first block in
the list of blocks.

[flang] Fix bug setting type from association expression

When an association selector is an expression, we get the type of the
associate-name from the type of the expression. If that is a derived
type, we were failing to get the derived type scope in copy of the
type that was made. That meant the component names were not resolved.

The fix is to copy the scope in the copy and move constructors of
`DerivedTypeSpec`. As a result, `DerivedTypeSpec::Instantiate` cannot
assume that the `scope_` is not set.

[flang] Improvements to name resolution in data statements

Handle variables in data statements differently from implied dos:
If a variable is first mentioned in a data statement, it is implicitly
declared in the current scope (and subsequent type declarations only
confirm the type).
In the implied do case, the only variables that can be implicitly
declared are the iteration variables. They must be created in the new
ImpliedDos scope. There must be one such scope for each data-stmt-object
because the variable name can be reused.

Resolve references to named constants, e.g. in complex-literal-constant
and data-stmt-value. This requires changing the handling of
named-constant-def as that is a definition, not a reference.
