[ASan] Add new options for asan_symbolize.py script.
...
The patch adds new features in asan-symbolizer script which are helpful for using ASan on embedded systems:
1) add cross-compile prefix for binutils
2) define path to sysroot with sanitized binaries
Features are enabled by command line options.
The patch also extends command line interface with help option.

[asan] Install asan_device_setup to bin/ when targetting Android.
...
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.
