[sanitizer] Use system unwinder in signal handlers on Android.
...
Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.
Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.

[asan] Enable frame pointer based unwinder on ARM.
...
This code works with AAPCS-style {fp, lr} frames. Unlike linux perf, it does
not unwind through code compiled with -mapcs-frame (which Clang does not
support anyway).

Revert three patches which were committed without explicit contribution

by their authors.
This may break builds where others added code relying on these patches,
but please *do not* revert this commit. Instead, we will prepare patches
which fix the failures.
Reverts the following commits:
r168306: "[asan] support x32 mode in the fast stack unwinder. Patch by H.J. Lu"
r168356: "[asan] more support for powerpc, patch by Peter Bergner"
r196489: "[sanitizer] fix the ppc32 build (patch by Jakub Jelinek)"

[ASan] Do not rely on malloc context in allocator reports.
...
Invoke a fatal stack trace unwinder when ASan prints allocator-relevant
error reports (double-free, alloc-dealloc-mismatch, invalid-free).
Thus we'll be able to print complete stack trace even if allocation/free
stacks are not stored (malloc_context_size=0).
Based on the patch by Yuri Gribov!
