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.

Extend documentation on preprocessing

IsSimplyContiguous

basic skeleton

Apply suggested improvements to mod-file.cc

Checks for new call13.f90 (15.4.2.2 explicit interfaces)

Argument checking, test fixing

Better argument checking

Better derived type compatibility checking

Treat externals as if implicitly interfaced

Extend IEEE_EXCEPTIONS module so tests still pass with argument checking

SAME_TYPE_AS and EXTENDS_TYPE_OF intrinsic inquiry functions

Define interfaces for most intrinsic subroutines

Better PASS arguments

More with PASS() argument

Prep for review

Pete Steinfeld f8cfc7cdf9 [flang] Fixed the declarations of IEEE_SUPPORT_FLAG and IEEE_SUPPORT_HALTING to
be functions rather than subroutines.  Note that Table 17.3 in the
standard summarizes the contents of IEEE_EXCEPTIONS with the details
specified in section 17.11.

Peter Steinfeld 8768a11d4c [flang] - ieee_exceptions.f90: I added all of the routines listed in table 17.3 of the standard that were not currently specified. I also re-ordered the routines to be in the same order as the standard.
- doconcurrent01.f90: I removed the custom versions of ieee_exceptions and
 iso_fortran_env.  I also fixed a typo in a comment.  Also, the use of the real
 standare interface caused one of the error messages to go away, so I fixed
 that.

Tim Keith 050a921aaf [flang] Fix errors in tests and predefined modules
There were many places in tests and predefined modules that had
incorrect code that we weren't detecting until now.

Most of the problems were deferred-shape arrays that should have
been implied-shape. For example:
`real, parameter :: a(:) = [1.0, 2.0]`
should have `(*)` rather than `(:)`.

There were also a few places with deferred-shape arrays that were
not allocatable/pointer or explicit-shape ones that were.
