Suppose two black holes were on a collision course with each other. As they get closer, their combined gravitational force causes them to accelerate. As they accelerate, due to relativity, their mass increases, as their masses increase, their gravitational force increases (right?) As their gravitational force increases, they accelerate more. So, could they eventually get to the speed of light?
Their mass would then be infinite, so it would take an infinite force to accelerate them, but their mass being infinite, their gravity would also be infinite, causing the force accelerating them to be infinite as well...

I've been out of physics class awhile, but I don't think their masses become infinite at the speed of light. Mass is constant. There is not infinite force. There are laws of conservation of mass and energy.
They would crash thunderously and probably shake the universe as we know it.

They would merge into one. Their masses do not get infinite. If we were are at rest and could somehow measure their masses, they would appear to approach infinity in OUR reference frame only. If you could somehow be riding on either one, the mass wouldn't increase.

Black hole has its own strong gravitional field.so any object which enters into it would not come back.When such blacholes combine then it would result into explosion.Because the gravitional field of each other will combine.There may sudden sparking and would led to explosion.

and their time will be slowed down infinitely too, so from the point of view of outside observer, they'll just collide with each other at normal speed.
besides, mass of black hole isn't infinite, it's just large for it's volume.

Just a guess,either like some storm systems where energy morphs into another storm sometimes hundreds of miles away.or rather maybe energy forces would make such impossible,like pushing two magnets together.

the holes will become one and will double in size
