Peter Klausler 0d9b0f642b [flang] IEEE_ARITHMETIC must imply USE IEEE_EXCEPTIONS
The intrinsic module IEEE_ARITHMETIC must incorporate the public
names from the intrisic module IEEE_EXCEPTIONS.  Rename IEEE_EXCEPTIONS
to __Fortran_ieee_exceptions so that it won't clash with the
nonintrinsic namespace, establish a new intrinic IEEE_EXCEPTIONS
module that USEs it, and add a USE to IEEE_ARITHMETIC.

Updated to use STREQUAL rather than ambiguous MATCHES in
the CMakeLists.txt file.

Andrzej Warzynski 75d74d99c7 Revert "[flang] IEEE_ARITHMETIC must imply USE IEEE_EXCEPTIONS"
This reverts commit b6a7600491. It caused
the following build failure:
```
ninja: error: dependency cycle: include/flang/__fortran_ieee_exceptions.mod -> include/flang/__fortran_ieee_exceptions.mod
```

See e.g.:
* https://lab.llvm.org/buildbot/#/builders/172/builds/9595

To reproduce:
```
cmake -G Ninja \
  -DLLVM_TARGETS_TO_BUILD=host \
  -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_ENABLE_PROJECTS="clang;flang" \
  ../../llvm
ninja check-flang

peter klausler f5ab4bfb5b [flang] Define IEEE_SCALB, IEEE_NEXT_AFTER, IEEE_NEXT_DOWN, IEEE_NEXT_UP
These functions were missing from the standard intrinsic module
IEEE_ARITHMETIC.  IEEE_SCALB is an alias for the standard intrinsic
function SCALE(), and the others are defined as new builtin intrinsic
functions.

peter klausler 8f16101c70 [flang] Accept & fold IEEE_SELECTED_REAL_KIND
F18 supports the standard intrinsic function SELECTED_REAL_KIND
but not its synonym in the standard module IEEE_ARITHMETIC
named IEEE_SELECTED_REAL_KIND until this patch.

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.
