[X86][Driver] Move all of the X86 feature flags to one spot in the Options.td file and pair them up with their negations.

[craig.topper]

Summary

It looks like at one time Options.td was in alphabetical order, but that looks to have long been broken. The result is that it all the no- x86 options got separated from their other friends for no good reason.

This patch puts them all together in one place with the no- paired with its none negated version.

I've kept all the SSE and AVX/AVX512 bits together since they represent a somewhat linear progression of features. The rest I just put in alphabetical order after.

LGTM. Thanks.
