Clang can generate LLVM IR for x86 without a registered x86 backend.

Tests fall into one of the following categories:
- The requirement was unnecessary
- Additional quoting was required for backslashes in paths (see "sed -e
's/\\/\\\\/g'") in the sanitizer tests.
- OpenMP used 'REQUIRES: shell' as a proxy for the test failing on
Windows. Those tests fail there reliably, so use XFAIL instead.
I tried not to remove shell requirements that were added to suppress
flaky test failures, but if I screwed up, we can add it back as needed.

directives.
'kmp_task_t' record type added a new field for 'priority' clause and
changed the representation of pointer to destructors for privates used
within loop-based directives.
Old representation:
typedef struct kmp_task { /* GEH: Shouldn't this be
aligned somehow? */
void *shareds; /**< pointer to block of
pointers to shared vars */
kmp_routine_entry_t routine; /**< pointer to routine
to call for executing task */
kmp_int32 part_id; /**< part id for the
task */
kmp_routine_entry_t destructors; /* pointer to function to
invoke deconstructors of firstprivate C++ objects */
/* private vars */
} kmp_task_t;
New representation:
typedef struct kmp_task { /* GEH: Shouldn't this be
aligned somehow? */
void *shareds; /**< pointer to block of
pointers to shared vars */
kmp_routine_entry_t routine; /**< pointer to routine
to call for executing task */
kmp_int32 part_id; /**< part id for the
task */
kmp_cmplrdata_t data1; /* Two known
optional additions: destructors and priority */
kmp_cmplrdata_t data2; /* Process
destructors first, priority second */
/* future data */
/* private vars */
} kmp_task_t;
Also excessive initialization of 'destructors' fields to 'null' was
removed from codegen if it is known that no destructors shal be used.
Currently a special bit is used in 'kmp_tasking_flags_t' bitfields
('destructors_thunk' bitfield).

If private variables require destructors call at the deletion of the
task, additional flag in task flags must be set. Patch fixes this
problem.
