modify C1 to notify method names with . not / as package separator

this means that when you simbreak a method you can use the same format
as when printed out by TraceCompilation  and hsdis. This also makes it
uniform with C2 so a given breakpoint works with both compilers.

reverted checkcast_arraycopy stub to return -1 ^ num_left_to_copy if copy fails

the generic code in C2 expects this result and its better to avoid the
maintenance/integration issues which arise from changing generic code
if we don't have a compelling performance reason
