Unlikely.  It would put too onerous a restriction on having the latest
version of GAS installed.  If the compiler needs to support a new
instruction, then obviously GAS has to know how to handle it, but GAS
shouldn't have to know about every CPU that's available for each
architecture in order for the compiler to support them.

That doesn't mean that GAS can't recognize CPU names, just that the
compiler should avoid such a feature.
