Hans Wennborg 67c6e5041b cmake: fix the compiler-rt build with MSVC 
This sets flags and excludes things that aren't working with MSVC yet,
allowing us to build the ASan runtime as part of the cmake build.

Sergey Matveev 9e3e80208f [sanitizer] Add a fast version of StackDepotGet() for use in LSan. 
Add a class that holds a snapshot of the StackDepot optimized for querying by
ID. This allows us to speed up LSan dramatically.

Sergey Matveev ef7db73e11 [sanitizer] Handle Die() in StopTheWorld. 
Handle calls to Die() from the tracer thread. Fixes a bug where a CHECK
could fail in the tracer thread, resulting in a call to AsanDie. The tracer
thread then exited and the parent process continued execution despite its
address space being in an unusable state.

Chandler Carruth 6b8d17bf35 It appears that glibc 2.13 has the same thread descriptor size as 2.11, 
bump up the inflection point to 2.14. If someone can tell me how to
actually figure out value for this, that would be awesome.

Anyways, this takes me to one ASan failure, one LSan failure, and three
TSan failures for 'check-all' on Linux.

Evgeniy Stepanov 0bb7577d89 [sanitizer] Split platform_limits_posix into system- and kernel-dependent parts. 
This change moves everything depending on kernel headers (mostly ioctl types
and ids) into a separate source file. This will reduce the possibility of
header conflict on various platforms (most importantly, older glibc versions).

This change also removes 2 deprecated ioctls, and symbolic ids for other bunch
of ambiguous ioctls (i.e. same id is shared by ioctls with different memory
behavior).
