[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.

Fix OMPT support for task frames, parallel regions, and parallel regions + loops
This patch makes it possible for a performance tool that uses call stack
unwinding to map implementation-level call stacks from master and worker
threads into a unified global view. There are several components to this patch.
include/*/ompt.h.var
Add a new enumeration type that indicates whether the code for a master task
for a parallel region is invoked by the user program or the runtime system
Change the signature for OMPT parallel begin/end callbacks to indicate whether
the master task will be invoked by the program or the runtime system. This
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
Change the signature for __kmp_join_call to take an additional parameter
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.
kmp_runtime.c:
Use the new information passed by __kmp_join_call to adjust the OMPT
parallel end callback invocations to carry the extra parameter indicating
whether the program or the runtime invokes the master task for a parallel
region.
ompt_internal.h:
Use the flavor of the parallel region API (GNU or Intel) to determine who
invokes the master task.

[llgo] build llgoi by default
Summary:
As llgoi is installed, it must be built or the install
target will fail; there is no implicit dependency.
Adding llgoi to "ALL" makes building llgo as part of an
entire LLVM distribution a bit friendlier: you can then
just do the typical "make && make install".

This can include objects that have complex state and need to be torn down intelligently (e.g. our SB* objects)
This will fail if the Python interpreter does not hold a valid thread state. So, acquire one, delete the session dictionary, and then let go of it on destruction
