This is the first part of upcoming asan support for s390 and s390x.
Note that there are bits for 31-bit support in this and subsequent
patches - while LLVM itself doesn't support it, gcc should be able
to make use of it just fine.

Large part of this change is required due to
https://code.google.com/p/android/issues/detail?id=61799
dlsym() crashes when symbol resolution fails, which means
we have to limit the interceptor list instead of relying on
runtime detection.
There are minor differencies in system headers, too.

struct stat defined in <asm/stat.h> is incorrect for x32. <asm/stat.h>
is included to get struct __old_kernel_stat. But struct __old_kernel_stat
isn't used for x86-64 nor x32. This patch includes <sys/stat.h> instead
of <asm/stat.h> and comments out size check of struct __old_kernel_stat
for x86-64.

Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time
assertions. This makes the dependency on the headers test-only and would allow
switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).

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).
