Subject: - parameter memory and active threads now part of kernel_info_t:

  Parameters are finalized at kernel launch, which means the contents
  of parameter memory are initialized. Kernel arguement names have a
  fixed order, hence same address should be assigned on subsequent
  kernel launches of same kernel in other streams provided the data size
  param_t::size of arguments for each kernel launch is identical (an
  assertion has been added to check this is true).

- passing regression
