Make compilation of other predefined module files depend on

iso_fortran_env.f90 depend on it but others could in the future.
Create the .f18.mod files by copying from the .mod files so that

[flang] Semantic checks to see if a DO variable is modified
I added infrastructure to SemanticsContext to track active DO variables
and the source locations where they appear in DO statements. I also
added code to semantics.[h,cc] to check to see if a DO variable is
already defined, and, if so, to emit an error message along with a
reference to the relevant DO construct. I also added calls to several
places where variables are defined to determine if the definitions are
happening in the context of an active DO construct.
I have not yet added the checks for DO variables being redefined when passing
them as actual arguments to dummy arguments with INTENT(OUT) or INTENT(INOUT).
I wanted to get these changes merged first and catch up with the other changes
in master.

- Renamed LICENSE to LICENSE.txt.
- NVIDIA Copyright lines have been removed.
- Initial lines for files follow the LLVM coding convention (file name on the first line; Emacs mode information on the first line).
- License references have been replaced with the abridged LLVM text.
- License information was removed from the test files.
- No file header was placed on test files (these weren't in most LLVM test files).
- License information was added to documentation files where it was missing.
We did not add brief file summaries to the initial line.
See http://llvm.org/docs/DeveloperPolicy.html#new-llvm-project-license-framework
for a description of the new license.
See http://llvm.org/docs/CodingStandards.html#file-headers

When dumping the parse tree, if there are analyzed expressions,
assignments, or call statements, include the Fortran form of those

This uses the same `AnalyzedObjectsAsFortran` object that unparsing
does so it applies to the same nodes.
We already do something like this for `Name` nodes as well as some
predefined types, so abstract it into an `AsFortran` function which
returns the Fortran source for a node that is to be included in the

[flang] Complex expression dump fixes
1. Dump negative parts in complex constants without parentheses
(-1., 0.) was dumped as ((-1.), 0.) from f18 expression format.
The latter format is only valid with the complex constructor extension
that is not supported by all compilers.
This commit ensure the former fromat is used in dumps so that dumps can
be used by all fortran compilers. It turns out the parenthesis added
by REAL::AsFortran are not required because operation lowering is
already taking care of this.
2. Dump evaluate::ComplexComponent with REAL/IMAG instead of %RE/%IM
f18 was failing to reparse its own dump in some cases involving
complex expressions like `-z**i`.
The reason was %RE and %IM were used to dump ComplexComponents.
%RE and %IM can only be used on designators but ComplexComponent can
contain arbitrary complex expressions.
Hence, %RE and %IM cannot be used to dump ComplexComponent.
This commit replace them with call to intrinsic function
REAL/IMAG.
Note that this may unfortunatly be unsafe if the user
shadowed REAL or IMAG but I do not see an easy way to solve
this... The current dump is not correct.

Add `IsDefinedAssignment` to decide based on types and ranks of lhs

The check that specific procedures of a generic are distinguishable
doesn't need to be done in `resolve-names.cc`. It can be deferred until
`check-declarations.cc` because it only depends on the symbol table.
Make use of `AttachDeclaration` when reporting errors
Refactor checks for different symbol details into separate functions
as they are getting more numerous.

[flang] Change AttachDeclaration to take reference instead of pointer
AttachDeclaration (and so also SayWithDeclaration) don't do anything
when passed a null pointer for the symbol and in all but one place they
are called the symbol can't be null. So change both function to take
`const Symbol &` rather than `const Symbol *`. Change it to handle
procedure bindings as well.
Add `SayWithDeclaration` to `CheckHelper` to simplify calling the one in
`evaluate` and prevent attaching the declaration when it would point at
the same line.

[flang] Combine GenericDetails and GenericBindingDetails
`GenericDetails` and `GenericBindingDetails` were almost identical:
the former has optional data members to handle the case when a specific
procedure or derived type has the same name as the generic symbol.
Most places they are handled the same way so it simplifies things to
have only one type. In the case where we want to know if it is a generic
binding (e.g. in `mod-file.cc`) we can check the kind of scope that owns
the symbol.
Save name from the generic binding for better location of error messages.

[flang] Refactor GenericKind
Change GenericKind from an enum class to a variant that includes the
`NumericOperator`, `LogicalOperator`, and `RelationalOperator` from `common`.
This allows for better tests like `IsIntrinsicOperator` (which used to
check for being in a range of the `GenericKind` enumeration) and
simplifies mapping the kind to a string representation.
