Jonathan Peyton ebf1830bb1 [OpenMP] Implement 5.0 memory management
* Replace HBWMALLOC API with more general MEMKIND API, new functions
  and variables added.
* Have libmemkind.so loaded when accessible.
* Redirect memspaces to default one except for high bandwidth which
  is processed separately.
* Ignore some allocator traits e.g., sync_hint, access, pinned, while
  others are processed normally e.g., alignment, pool_size, fallback,
  fb_data, partition.
* Add tests for memory management

Jonathan Peyton 76f3980a20 [OpenMP] Add omp_get_device_num() and update several other device API functions
Add omp_get_device_num() function for 5.0 which returns the number of the
device the current thread is running on. Currently, we are leaving it to the
compiler to handle this properly if it is called inside target.

Also, did some cleanup and updating of duplicate device API functions (in both
libomp and libomptarget) to make them into weak functions that check for the
symbol from libomptarget, and will call the version in libomptarget if it is
present. If any additional device API functions are implemented also in
libomptarget in the future, we should add the dlsym calls to the host functions.
Also, if the omp_target_* functions are to be implemented for the host (this has
been requested), they should attempt to call the libomptarget versions as well.

Roman Lebedev 781a0896b0 [OpenMP] Fixes for LIBOMP_OMP_VERSION=45/40
Summary:
I have discovered this because i wanted to experiment with
building static libomp (with openmp-4.0 support only)
for debugging purposes.

There are three kinds of problems here:
1. `__kmp_compare_and_store_acq()` simply does not exist.
   It was added in D47903 by @jlpeyton.
   I'm guessing `__kmp_atomic_compare_store_acq()` was meant.
2. In `__kmp_is_ticket_lock_initialized()`,
   `lck->lk.initialized` is `std::atomic<bool>`,
   while `lck` is `kmp_ticket_lock_t *`.
   Naturally, they can't be equality-compared.
   Either, it should return the value read from `lck->lk.initialized`,
   or do what `__kmp_is_queuing_lock_initialized()` does,
   compare the passed pointer with the field in the struct
   pointed by the pointer. I think the latter is correct-er choice here.
3. Tests were not versioned.
   They assume that `LIBOMP_OMP_VERSION` is at the latest version.

This does not touch LIBOMP_OMP_VERSION=30. That is still broken.

Michal Gorny 276df88154 [test] [runtime] Permit omp_get_wtick() to return 0.01
Increase the range for omp_get_wtick() test to allow for 0.01
(from <0.01).  This is needed for NetBSD where it returns exactly that
value due to CLOCKS_PER_SEC being 100.  This should not cause
a significant difference from e.g. FreeBSD where it is 128,
and especially from Linux where CLOCKS_PER_SEC is apparently meaningless
and sysconf(_SC_CLK_TCK) gives 100 as well.

Jonathan Peyton 92ca61884b [OpenMP] Initial implementation of OMP 5.0 Memory Management routines
Implemented omp_alloc, omp_free, omp_{set,get}_default_allocator entries,
and OMP_ALLOCATOR environment variable.

Added support for HBW memory on Linux if libmemkind.so library is accessible
(dynamic library only, no support for static libraries).
Only used stable API (hbwmalloc) of the memkind library
though we may consider using experimental API in future.

The ICV def-allocator-var is implemented per implicit task similar to
place-partition-var.  In the absence of a requested allocator, the uses the
default allocator.

Predefined allocators (the only ones currently available) are made similar
for C and Fortran, - pointers (long integers) with values 1 to 8.

Jonathan Peyton 7f976d556a Fix memory error in case of reinit using kmp_set_defaults() for lock code.
The lock tables were being reallocated if kmp_set_defaults() was called.
In the env_init code it says that the user should be able to switch between
different KMP_CONSISTENCY_CHECK values which is what this change enables.

Jonathan Peyton f83ae31caf Adding new kmp_aligned_malloc() entry point
This change adds a new entry point,
kmp_aligned_malloc(size_t size, size_t alignment), an entry point corresponding
to kmp_malloc() but with the capability to return aligned memory as well.
Other allocator routines have been adjusted so that kmp_free() can be used for
freeing memory blocks allocated by any kmp_*alloc() routine, including the new
kmp_aligned_malloc() routine.

Jonathan Peyton 614c7ef81c OpenMP Initial testsuite change to purely llvm-lit based testing
This change introduces a check-libomp target which is based upon llvm's lit
test infrastructure. Each test (generated from the University of Houston's
OpenMP testsuite) is compiled and then run. For each test, an exit status of 0
indicates success and non-zero indicates failure. This way, FileCheck is not
needed. I've added a bit of logic to generate symlinks (libiomp5 and libgomp)
in the build tree so that gcc can be tested as well.  When building out-of-
tree builds, the user will have to provide llvm-lit either by specifying
-DLIBOMP_LLVM_LIT_EXECUTABLE or having llvm-lit in their PATH.
