Vitaly Buka fe894453fe Unpoison stack before resume instruction
Summary:
Clang inserts cleanup code before resume similar way as before return instruction.
This makes asan poison local variables causing false use-after-scope reports.

__asan_handle_no_return does not help here as it was executed before
llvm.lifetime.end inserted into resume block.

To avoid false report we need to unpoison stack for resume same way as for return.
