[PPC64LE] More vector swap optimization TLC

This makes one substantive change and a few stylistic changes to the
VSX swap optimization pass.

The substantive change is to permit LXSDX and LXSSPX instructions to
participate in swap optimization computations.  The previous change to
insert a swap following a SUBREG_TO_REG widening operation makes this
almost trivial.

I experimented with also permitting STXSDX and STXSSPX instructions.
This can be done using similar techniques:  we could insert a swap
prior to a narrowing COPY operation, and then permit these stores to
participate.  I prototyped this, but discovered that the pattern of a
narrowing COPY followed by an STXSDX does not occur in any of our
test-suite code.  So instead, I added commentary indicating that this
could be done.

Other TLC:
 - I changed SH_COPYSCALAR to SH_COPYWIDEN to more clearly indicate
 the direction of the copy.
 - I factored the insertion of swap instructions into a separate
 function.

Finally, I added a new test case to check that the scalar-to-vector
loads are working properly with swap optimization.

    enables a performance tool using call stack unwinding to handle these two
    cases differently. For this case, a profiler that uses call stack unwinding
    needs to know that the call path prefix for the master task may differ from
    those available within the begin/end callbacks if the program invokes the
    master.

kmp.h

  indicating the fork_context type. This is needed to supply the OMPT parallel
  end callback with information about whether the compiler or the runtime
  invoked the master task for a parallel region.

kmp_csupport.c
  Ensure that the OMPT task frame field reenter_runtime_frame is properly set
    and cleared before and after calls to fork and join threads for a parallel
    region.
  Adjust the code for the new signature for __kmp_join_call.
  Adjust the OMPT parallel begin callback invocations to carry the extra
    parameter indicating whether the program or the runtime invokes the master
    task for a parallel region.

kmp_gsupport.c
  Apply all of the analogous changes described for kmp_csupport.c for the GOMP
    interface
  Add OMPT support for the GOMP combined parallel region + loop API to
    maintain the OMPT task frame field reenter_runtime_frame.
