This patch adds support for tsan on aarch64-linux with 42-bit VMA
(current default config for 64K pagesize kernels).  The support is
enabled by defining the SANITIZER_AARCH64_VMA to 42 at build time
for both clang/llvm and compiler-rt.  The default VMA is 39 bits.

The ignore_lib{0,1,3}.cc is now disable for aarch64 (although for newer
kernels they do pass) until the all the buildbots have the fix.
