KMP_API_NAME_GOMP_PARALLEL_SECTIONS function was missing the task frame support.
This patch introduced a fix responsible to set properly the exit_frame of
the innermost implicit task that corresponds to the parallel section construct,
as well as the enter_frame of the task that encloses the mentioned implicit task.

This patch also introduced a simple test case sections_serialized.c that contains
serialized parallel section construct and validates whether the mentioned
task frames are set correctly.

The minor code refactorization introduces the TASK_TIED constant inside
kmp_gsupprot.cpp as a replacement for the literal value 1.
The mentioned constant is now used in both kmp_tasking.cpp and
kmp_gsupport.cpp files.

GOMP depobjs are represented as a two intptr_t array. The first
element is the base address of the dependency and the second element
is the flag indicating the type the depobj represents.

This is the first of seven patches that implements OMPD, a debugging interface to support debugging of OpenMP programs.
It contains support code required in "openmp/runtime" for OMPD implementation.

Implement the remaining GOMP_* functions to support task reductions
in taskgroup, parallel, loop, and taskloop constructs.  The unused mem
argument to many of the work-sharing constructs has to do with the
scan() directive/ inscan() modifier.  If mem is set, each function
will call KMP_FATAL() and tell the user scan/inscan is unsupported.  The
GOMP reduction implementation is kept separate from our implementation
because of how GOMP presents reduction data and computes the reductions.
GOMP expects the privatized copies to be present even after a #pragma
omp parallel reduction(task:...) region has ended so the data is stored
inside GOMP's uintptr_t* data pseudo-structure.  This style is tightly
coupled with GCC compiler codegen.  There also isn't any init(),
combiner(), fini() functions in GOMP's codegen so the two
implementations were to disparate to try to wrap GOMP's around our own.

and __kmpc_end_masked. The "master" construct is deprecated. Changed
proc-bind keyword from "master" to "primary". Use of both master
construct and master as proc-bind keyword is still allowed, but
deprecated.

Remove references to "master" in comments and strings, and replace
with "primary" or "primary thread". Function names and variables were
not touched, nor were references to deprecated master construct. These
can be updated over time. No new code should refer to master.

Same script as D95318. Test files are excluded.

This patch partially prepares the runtime source code to be built with
-Wconversion, which should trigger warnings if any implicit conversions
can possibly change a value. For builds done with icc or gcc, all such
warnings are handled in this patch. clang gives a much longer list of
warnings, particularly for sign conversions, which the other compilers
don't report. The -Wconversion flag is commented into cmake files, but
I'm not going to turn it on. If someone thinks it is important, and wants
to fix all the clang warnings, they are welcome to.

Types of changes made here involve either improving the consistency of types
used so that no conversion is needed, or else performing careful explicit
conversions, when we're sure a problem won't arise.

Patch is a combination of changes by Terry Wilmarth and Johnny Peyton.

D91692 missed various locations in kmp_gsupport, where the scope for
OMPT_STORE_RETURN_ADDRESS is too narrow, i.e. the scope ends before the OMPT
callback is called in some nested function.

This patch fixes the scoping issue, so that all OMPT tests pass, when the
tests are built with gcc.
