x86: correct what gets disabled by certain ".arch .no*"
Features with prereqs as well as features with dependents cannot re-use
CPU_*_MASK for the 3rd argument of SUBARCH() - they need to use
CPU_ANY_*_MASK in order to avoid disabling too many (when there are
prereqs) and/or too few (when there are dependents) features.
Generally any CPU_ANY_*_MASK which exist should not remain unused.
Exceptions are
- FISTTP which has no corresponding entry in cpu_arch[],
- IAMCU which is a base architecture and hence uses ARCH(), not
SUBARCH() (only extensions can be disabled, but unlike for Cpu*86 it
would be a little more clumsy to suppress generating of the #define).
