[ubsan] Fix for vptr check
Summary:
There can be a situation when vptr not initializing
by constructor of the object, and has a junk data
which should be properly checked, because c++ standard
says:
"If the new-initializer is omitted, the object is default-initialized (8.5).
[ Note: If no initialization is performed,
the object has an indeterminate value. — end note ]

There might be a situation when ASan initializing later

[asan/lsan] Avoid possible deadlock in dynamic ASan runtime thread initialization.
There is possible deadlock in dynamic ASan runtime when we dlopen() shared lib
which creates a thread at the global initialization stage. The scenario:
1) dlopen grabs a GI_pthread_mutex_lock in main thread.
2) main thread calls pthread_create, ASan intercepts it, calls real pthread_create
and waits for the second thread to be "fully initialized".
3) Newly created thread tries to access a thread local disable_counter in LSan
(to complete its "full initialization") and hangs in tls_get_addr_tail, because
it also tries to acquire GI_pthread_mutex_lock.
The issue is reproducible on relative recent Glibc versions e.g. 2.23.

Add mmap/munmap interceptors.
Some allocators may use mmap for their local pools that may cause false positive
reports because LSan currently doesn't intercept mmap call mainly due to its
complexity (we don't know whether a particular mmap would contain live pointers).
However for some cases (e.g. anonymous rw mmaps) we can guess that they would
contain live pointers thus we can add them into root regions. Thus, now we
intercept mmap/munmap calls, add anonymous rw mappings into root regions and
call real mmap.
