Workaround PR68256 on AArch64

> This is causing a bootstrap comparison failure in gcc/go/gogo.o.

I've had a look at this and the trigger is the
aarch64_use_constant_blocks_p change which appears to be causing a
bootstrap comparison failure because of differences to offsets when
built with debug and without debug. I don't think the problem is
specifically in the backend but this needs some careful
investigation. For now, in the interest of go bootstraps continuing on
trunk - I'm proposing a patch that partially rolls back the change in
aarch64_use_constant_blocks_p and am still looking into the issue but
it will take me some more time to get to the bottom of the issue.

Bootstrapped on aarch64-none-linux-gnu including (c,c++ and go) -
testing finished ok.

Update libsanitizer obstack interceptors

New obstack uses sensible types, size_t instead of int for length
params.  Since libsanitizer does not use prototypes from obstack.h to
call the real functions, it's necessary to update the libsanitizer
function declarations emitted by the INTERCEPTOR macro.

* sanitizer_common/sanitizer_common_interceptors.inc: Update size
params for _obstack_begin_1, _obstack_begin, _obstack_newchunk
interceptors.
* configure.ac: Substitute OBSTACK_DEFS.
* asan/Makefile.am: Add OBSTACK_DEFS to DEFS.
* tsan/Makefile.am: Likewise.
* configure: Regenerate.
* Makefile.in: Regenerate.
* asan/Makefile.in: Regenerate.
* interception/Makefile.in: Regenerate.
* libbacktrace/Makefile.in: Regenerate.
* lsan/Makefile.in: Regenerate.
* sanitizer_common/Makefile.in: Regenerate.
* tsan/Makefile.in: Regenerate.
* ubsan/Makefile.in: Regenerate.

Correct libvtv obstack use

Fixes a compile error with both old and new obstacks due to
obstack_chunk_free having the wrong signature.  Also, setting chunk
size and alignment before obstack_init is pointless since they are
overwritten.

* vtv_malloc.cc (obstack_chunk_free): Correct param type.
(__vtv_malloc_init): Use obstack_specify_allocation.

New obstack_next_free is not an lvalue

New obstack.h casts obstack_next_free to (void *), resulting in it
being a non-lvalue, and warnings on pointer arithmetic.

gcc/
* gensupport.c (add_mnemonic_string): Make len param a size_t.
(gen_mnemonic_setattr): Make "size" var a size_t.  Use
obstack_blank_fast to shrink obstack.  Cast obstack_next_free
return value.
gcc/objc/
* objc-encoding.c (encode_aggregate_within): Cast obstack_next_free
return value.
