peter klausler 4fede8bc8a [flang] Implement derived type description table encoding
Define Fortran derived types that describe the characteristics
of derived types, and instantiations of parameterized derived
types, that are of relevance to the runtime language support
library.  Define a suite of corresponding C++ structure types
for the runtime library to use to interpret instances of the
descriptions.

Create instances of these description types in Semantics as
static initializers for compiler-created objects in the scopes
that define or instantiate user derived types.

Delete obsolete code from earlier attempts to package runtime
type information.

peter klausler 5c9aca1e93 [flang] Descriptor-based I/O using wrong size for contiguous unformatted I/O
The descriptor-based I/O routine was using the size of the descriptor
rather than the size of the described data for the transfer.  Fix,
and add a comment to the relevant API.

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.
