This patch contains the clang-format and cleanup of the entire code base. Some
of clang-formats changes made the code look worse in places. A best effort was
made to resolve the bulk of these problems, but many remain. Most of the
problems were mangling line-breaks and tabbing of comments.

This patch doesn't affect D19878's context. So D19878 still cleanly applies.

Use of #ifdef OMPT_DEBUG was causing messages to be generated under normal
operation when the OpenMP library was compiled with KMP_DEBUG enabled.
Elsewhere, KMP_DEBUG evaluates assertions, but never produces messages during
normal operation. To avoid this inconsistency, set OMPT_DEBUG using a cmake
variable LIBOMP_OMPT_DEBUG.
While I was editing the associated ompt-specific.h and ompt-general.c files,
make the spacing and comments consistent.

The problem is that the ompt_tool() function (which must be implemented by a
performance tool) should be defined in the RTL as well to cover the case when
the tool is not present in the address space of the process. This functionality
is accomplished with weak symbols in Unices. Unfortunately, Windows does not
support weak symbols.
The solution in these changes is to grab the list of all modules loaded by the
process and then search for symbol "ompt_tool()" within them. The function
ompt_tool_windows() performs the search of the ompt_tool symbol. If ompt_tool is
found, then its return value is used to initialize the tool. If ompt_tool is not
found, then ompt_tool_windows() returns NULL and OMPT is thus, disabled.
While doing these changes, the OMPT_SUPPORT detection in CMake was changed to
test for the required featuers for OMPT_SUPPORT, namely: builtin_frame_address()
existence, weak attribute existence and psapi.dll existence. For
LIBOMP_HAVE_OMPT_SUPPORT to be true, it must be that the builtin_frame_address()
intrinsic exists AND one of: either weak attributes exist or psapi.dll exists.
Also, since Process Status API is used I had to add new dependency -- psapi.dll
to the library dependency micro test.

The OMPT specification has changed. This revision brings the LLVM OpenMP
implementation up to date.
Technical overview of changes:
Previously, a public weak symbol ompt_initialize was called after the OpenMP
runtime is initialized. The new interface calls a global weak symbol ompt_tool
prior to initialization. If a tool is present, ompt_tool returns a pointer to
a function that matches the signature for ompt_initialize. After OpenMP is
initialized the function pointer is called to initialize a tool.
Knowing that OMPT will be enabled before initialization allows OMPT support to
be initialized as part of initialization instead of back patching
initialization of OMPT support after the fact.
Post OpenMP initialization support has been generalized moves from
ompt-specific.c into ompt-general.c, since the OMPT initialization logic is no
longer implementation specific.
