Maybe assert that twenty_four_bits does indeed only use 24 bits?

Right now we don't check so the assert would not always be true (though it
always is for any sensible regexp).  I will add the assert when I add the check
(it's on the TODO list).

+  uint32_t word = ((twenty_four_bits << BYTECODE_SHIFT) | byte);
   ASSERT(pc_ <= buffer_.length());
-  if (pc_ == buffer_.length()) {
+  if (pc_  + 3 >= buffer_.length()) {
     Expand();
   }
-  buffer_[pc_++] = byte;
+  Store32(buffer_.start() + pc_, word);
+  pc_ += 4;
 }
