Basically it makes both '-fasm' and '-fgnu-keywords' (and their no- variants) synonyms for explicitly enabling or disabling GNU-extension keywords. This is actually the behavior of -fasm in GCC, their -fgnu-keywords is a more limited flag. If people see real benefit to supporting this distinction I can, but it didn't seem productive. It also doesn't make a lot of logical sense. 

GCC's behavior really doesn't make any sense, but this seems like a reasonable (sane) approximation.

Please update the PCH reader and writer to serialize the GNUKeywords bit. Otherwise, looks good!
