TSan's Android `__get_tls()` and `TLS_SLOT_TSAN` can be used by other sanitizers as well (see https://reviews.llvm.org/D32649), this change moves them to sanitizer_common.
I picked sanitizer_linux.h as their new home.
In the process, add the 32-bit versions for ARM, i386 & MIPS.

Can the address of `__get_tls()[TLS_SLOT_TSAN]` change in between the calls?
I am not sure if there is a need to repeat the construct as opposed to using a variable. So I left things as they were.

Testing on my side was restricted to a successful cross-compilation.
