[ASan] Enable -asan-stack-dynamic-alloca by default. By default, store all local variables in dynamic alloca instead of static one. It reduces the stack space usage in use-after-return mode (dynamic alloca will not be called if the local variables are stored in a fake stack), and improves the debug info quality for local variables (they will not be described relatively to %rbp/%rsp, which are assumed to be clobbered by function calls). llvm-svn: 228336
