cpplint.py wants to prohibit "volatile" variable types but allow the volatile keyword on a line of inline assembly. However, it only allows __asm__ volatile, it rejects asm volatile.

Let's update the check in CheckForMongoVolatile() in cpplint.py. Now, it bans volatile unless it sees __asm__ specifically. Instead, it should ban volatile unless the line matches the _MATCH_ASM regex.
