[ubsan] fix vptr test on ARM

XFAIL ptrace test on arm

The patch adds better target_triple and target_arch defaults for lit tests,
which allows us to XFAIL tests based on architecture.

Was:
  target_triple = LLVM_DEFAULT_TARGET_TRIPLE
  target_arch = HOST_ARCH

Now:
  target_triple = COMPILER_RT_TEST_TARGET_TRIPLE
                , otherwise LLVM_DEFAULT_TARGET_TRIPLE
  target_arch = first item in COMPILER_RT_TEST_TARGET_TRIPLE

Use 64-bit pointer to unwind stack for x86-64

X32 uses ILP32 data model in 64-bit hardware mode.  This patch always
uses 64-bit pointer to unwind stack for x86-64.

Cast pointers to uptr when calling internal_syscall

For Linux/x86-64, pointers passed to internal_syscall should be casted
to uptr first.  Otherwise, they won't be properly extended to 64-bit for
x32.

[asan] Fix x86 asm instrumentation to preserve flags.

This change also enables asm instrumentation in asan tests that was
accidentally disabled yearlier, and adds a sanity test for that.

[msan] Chained origins re-design.

Generalize StackDepot and create a new specialized instance of it to
efficiently (i.e. without duplicating stack trace data) store the
origin history tree.

This reduces memory usage for chained origins roughly by an order of
magnitude.

Most importantly, this new design allows us to put two limits on
stored history data (exposed in MSAN_OPTIONS) that help avoid
exponential growth in used memory on certain workloads.

See comments in lib/msan/msan_origin.h for more details.
