[asan] add two new hidden compile-time flags for asan: asan-instrumentation-with-call-threshold and asan-memory-access-callback-prefix. This is part of the workaround for PR17409 (instrument huge functions with callbacks instead of inlined code). These flags will also help us experiment with kasan (kernel-asan) and clang git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206383 91177308-0d34-0410-b5e6-96231b3b80d8

[asan] properly instrument memory accesses that have small alignment (smaller than min(8,size)) by making two checks instead of one. This may slowdown some cases, e.g. long long on 32-bit or wide loads produced after loop unrolling. The benefit is higher sencitivity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209508 91177308-0d34-0410-b5e6-96231b3b80d8
