[PowerPC][asan] Update asan to handle changed memory layouts in newer kernels
In more recent Linux kernels with 47 bit VMAs the layout of virtual memory for powerpc64 changed causing the address sanitizer to not work properly. This patch adds support for 47 bit VMA kernels for powerpc64 and fixes up test cases. https://reviews.llvm.org/D40908 There is an associated patch for trunk. Tested on several 4.x and 3.x kernel releases. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@320110 91177308-0d34-0410-b5e6-96231b3b80d8
