BTW, below is one (untested) way to organize gcd_22. Wants an sub_mddmmss,

typedef struct {
mp_limb_t d[2];
} mp_double_limb_t;
I believe one should use separate mp_limb_t variables, not an array, as
an array will force things to memory before field accesses.
I haven't looked at the rest of the code yet. Note that we already have
asm variants for armv6t2, armv8a, power9, and x86-64. The loops are
proably OK, the exit states are somewhat confused.
