[ASan] Make insertion of version mismatch guard configurable
By default ASan calls a versioned function
`__asan_version_mismatch_check_vXXX` from the ASan module constructor to
check that the compiler ABI version and runtime ABI version are
compatible. This ensures that we get a predictable linker error instead
of hard-to-debug runtime errors.
Sometimes, however, we want to skip this safety guard. This new command
line option allows us to do just that.
