Call __asan_free_hook() before marking the chunk quarantinned
...
Summary:
With this change, the user may safely call __asan_get_ownership()
from malloc/free hooks and assume it would return "true". If there is a
realloc/free race, free hook might be called twice, but I think it's acceptable,
as it's a data race and would later be reported anyway.
This change also fixes a bug when failing realloc incorrectly marked the
original memory as "quarantinned".

[asan] Change the way we report the alloca frame on stack-buff-overflow.
...
Before: the function name was stored by the compiler as a constant string
and the run-time was printing it.
Now: the PC is stored instead and the run-time prints the full symbolized frame.
This adds a couple of instructions into every function with non-empty stack frame,
but also reduces the binary size because we store less strings (I saw 2% size reduction).
This change bumps the asan ABI version to v3.
compiler-rt part, llvm part will follow.
Example of report (now):

[ASan] Fix an error on invalid deallocation in ASan allocator. When ASan checks if memory freed by user was indeed previously allocated, it first does an atomic write to presumed location of chunk header. This is wrong, as if the free is invalid, we may overwrite some valuable data (like other fields of the chunk header). Fix this by using atomic_compare_exchange instead.

This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or

Instrumentation is done with two 1-byte checks

__asan_report_load_n(addr, real_size) or
__asan_report_store_n(addr, real_size)
is called.
