when compiling with gcc or clang numerous warnings concerning the usage
of extern "C" linkage. All the __kmp_itt_sync* variables are declared
like: extern "C" type __kmp_itt_sync... = definition; through various macros.
This note from cppreference.com explains why this is a problem.
// From http://en.cppreference.com/w/cpp/language/language_linkage
extern "C" int x; // a declaration and not a definition
// The above line is equivalent to extern "C" { extern int x; }
extern "C" { int x; } // a declaration and definition
Since the __kmp_itt_* variables are being declared and defined, these variables
should use the bracketed version instead.

This change changes kmp_bstate.old_tid to sign integer instead of unsigned integer.
It also defines two new macros KMP_NSEC_PER_SEC and KMP_USEC_PER_SEC which lets us take
control of the sign (we want them to be longs). Also, in kmp_wait_release.h, the byteref()
function's return type is changed from char to unsigned char.

The following change is needed to suppress the "variable 'retval' is used
uninitialized whenever 'if' condition is false" warnings in runtime/src/kmp_csupport.c.
This change just initializes 'retval' to 0.

in kmp_wait_release.h, there were some constructors where the initialization
lists were out of order with the member declarations inside the class. This
patch just reorders the initialization list so the compiler doesn't complain.

This change produces a dynamic library named libomp instead of
libiomp5. Similar to the CMake change, it produces symlinks of libiomp5
in the exports/ directory for Unix systems and copies for Windows.
llvm-svn: 238720
This change has the CMake build system create a dynamic library named
libomp instead of libiomp5. Also any reference to libiomp is replaced
with libomp. One can still use the LIBOMP_LIB_NAME variable to enforce
a different name, and everything will still work as expected. An important
note is that libiomp5 and libgomp symlinks are created at install time when
on Unix systems. On Windows, copies are created with the legacy names.
llvm-svn: 238715
These changes are mostly in comments, but there are a few
that aren't. Change libiomp5 => libomp everywhere. One internal
function name is changed in kmp_gsupport.c, and in kmp_i18n.c, the
static char[] variable 'name' is changed to "libomp".

The CMAKE_OSX_ARCHITECTURES CMake variable allows users to build
universal fat libraries that contain both i386 and x86_64 code. These
changes allow this build by having the z_Linux_asm.s file detect the architecture
itself instead of receiving it through the build system.
Also, there was a LIBOMP_OSX_ARCHITECTURES CMake variable added to allow
people to only build libomp as a fat library and not the entire LLVM/Clang system.

A while back, Hal suggested updating the GUIDEDLL_EXPORTS macro guard to
a more descriptive name. It represents a dynamic library build so
KMP_DYNAMIC_LIB is a more suitable name.

Removing unnecessary spaces. For CACHE variables, putting the description string
on its own line which mimics libcxx. There are no logic changes.

The fix simply syncs up the new threads to have the same task_state and
task_team as the old threads. The master thread is skipped,
because it shouldn't at this point have the team's task_team value yet
-- it should still have parent_team's task_team. It gets pointed at
the new team's task_team later, after __kmp_allocate_team returns, and
the master has stored a memo of it's old task_state.

Cached CMake variables need to have a prefix so they don't collide with other
projects. This change (a lot of simple changes) simply prefixes cached variables
with LIBOMP_ and sets all of these variables to UPPERCASE which is convention.
e.g., os => LIBOMP_OS, ompt_support => LIBOMP_OMPT_SUPPORT.

When calling the testsuite, clang could not locate omp.h. The
proper environment variable was modified to include:
exports/common/omp.h. Documentation was also updated to be more
clear.

This patch integrates the libiomp CMake build system into the LLVM CMake build
system so that users can checkout libiomp into the projects directory of llvm
and build llvm,clang, and libiomp all together. These changes specifically
introduce a new install target which will put libraries and headers into the
correct locations when either a standalone build or part of llvm.
The copy_recipe() method has been removed in favor of the POST_BUILD method
to move headers into the exports subdirectory. And lastly, the MicroTests.cmake
file was refactored which led to simpler target dependencies and a new target,
make libiomp-micro-tests, which performs the 5 small tests (test-relo,
test-touch, etc.) when called.
