<br>
These patches improve ASan support for swapcontext() and friends mainly<br>
focusing on eliminating false positives caused by throwing and catching<br>
exceptions when on a custom user stack.<br>
This is achieved by adding ability to AsanThread to change current<br>
stack (in an async-safe way).<br>
<br>
Some of the things that are still not fully supported:<br>
 - swapcontext() and fake stacks<br>
 - changing context from signal handlers<br>
 - changing context using longjmp()<br>
 - final context change via ucontext_t::uc_link<br>
<br>
On x64 Linux 'make check-all' passes.<br>
<br>
