[Sanitizer] fix signed/unsigned compare warnings in sanitizer_stacktrace_test. Build sanitizer_common tests with -Werror as we use predictable just-built Clang for building them

Summary:
The test sets up fake x86-style fp+retaddr frames, since that's all the
unwinder works with.

[ASan] temporarily disable alloc_dealloc_mismatch on Mac, since the previous commit caused error reports in gTest.

Because the interceptors will reside in a dylib, not the main executable, we can't just declare them,
but must use the interposition machinery.
Fix the test expectations in large_func_test.cc affected by the change.
This CL should make our Mac buildbots green.

that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.

Using > instead of >= ensures that each frame deref makes progress and
that we eventually terminate.

[ASan] Delete asan/dynamic dir and temporarily move the interposers declarations to asan_intercepted_functions.h
Now that we have only one dependency on asan_intercepted_functions.h, we can unite that code with the interceptors declarations in asan_interceptors.cc and get rid of asan_intercepted_functions.h

This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or
packed structures.
Instrumentation is done with two 1-byte checks
(first and last bytes) and if the error is found
__asan_report_load_n(addr, real_size) or
__asan_report_store_n(addr, real_size)
is called.

execle(argv[0], ...) is wrong, because argv[0] may contain a PATH-resolvable
program name. Execute /proc/self/exe instead.
