[libsanitizer] Run the callback on a separate stack in StopTheWorld.
...
Currently the callback runs on the caller's stack. If this stack
contains values that have gone out of scope, and we are not super careful, those
values can propagate into global variables (the libc sigaction() in particular
has a side effect that can lead to this). This has caused false negatives in
leak checking code.
Changes: map a separate stack space for the tracer thread. Also, move some
globals into local scope (they had no business being global anyway).

[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):

...
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
sanitizer runtime is present.
* libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
a C++ ABI library, and is always linked in.
* libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
C++ ABI library, and is only linked in when linking a C++ binary.
The Darwin ubsan runtime is unchanged.

Create a coverage initialization function.
...
This function replaces the call of `atexit' from being generated in the compile
units. Basically, it registers the "writeout" and "flush" functions (if
present). It will generate calls to the `atexit' function for cleanups and final
writeout functions, but only once. This is better than checking for `main',
because a library may not have a `main' function in it.

Add a way to register and execute "writeout" functions.
...
It may be prohibitively expensive to write out >1000 files at the same time. So
we would rather emit them serially. These functions allow the GCOV
implementation to register the functions that writeout the GCOV information per
compile unit. At exit, they are written.

Add some GCOV functions that register all of the __llvm_gcov_flush() functions.
...
The __llvm_gcov_flush() functions only work for the local compile unit. However,
when __gcov_flush() is called, the user expects all of the counters to be
flushed, not just the ones in the current compile unit.
This adds some library functions that register the flush functions. It also
defined __gcov_flush() so that loops through that list and calls the functions.
