Properly generate lists of exported symbols for sanitizer runtimes
...
This change adds a Python script that is invoked for
the just-built sanitizer runtime to generate the list of exported symbols
passed to the linker. By default, it contains interceptors and sanitizer
interface functions, but can be extended with tool-specific lists.

cmake: fix the compiler-rt build with MSVC

Handle calls to Die() from the tracer thread. Fixes a bug where a CHECK

thread then exited and the parent process continued execution despite its
address space being in an unusable state.

[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).
