[asan] Fix dynamic allocas unpoisoning on PowerPC64. For PowerPC64 we cannot just pass SP extracted from @llvm.stackrestore to _asan_allocas_unpoison due to specific ABI requirements (http://refspecs.linuxfoundation.org/ELF/ppc64/PPC-elf64abi.html#DYNAM-STACK). This patch adds the value returned by @llvm.get.dynamic.area.offset to extracted from @llvm.stackrestore stack pointer, so dynamic allocas unpoisoning stuff would work correctly on PowerPC64. Patch by Max Ostapenko. Differential Revision: http://reviews.llvm.org/D15108 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@254707 91177308-0d34-0410-b5e6-96231b3b80d8
