Semantic checks to see if a DO variable is modified

Pete Steinfeld 611db270f6 [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.

Gary Klimowicz 9e7548ab31 [flang] Flang relicensing changes for LLVM Apache 2.0 license 
This changes the license information in many of the flang source files.
- 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
for a description of the new LLVM standard file header.

Tim Keith 37de6803e3 [flang] Include analyzed exprs in parse tree dump 
When dumping the parse tree, if there are analyzed expressions,
assignments, or call statements, include the Fortran form of those
in the dump.

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
dump.

Tim Keith e567bf9f5e [flang] Support for type-bound operators and assignment 
Add `ArgumentAnalyzer::FindBoundOp` to look for an operator or
assignment definition in the type of each operand. Then `TryBoundOp`
checks if it is actually applicable.

Change ResolveGeneric to handle type-bound operators: the `adjustActuals`
function passed in handles the difference between these and normal
type-bound procedures. For operators, either operand may be the passed-
object argument. For procedures we know which one it is.

Extract `GetDerivedTypeSpec`, `GetBindingResolution`, and
`OkLogicalIntegerAssignment` into separate functions to simplify the
logic of the calling functions.
