1021260ca9 Make verifiable a DSO and add NAME_SUFFIX support 
Build option DSO=1 generates libverifiable.so which can be
used to reduce the combined binary size.

Build option NAME_SUFFIX can be used to a add suffix to all
generated binaries. e.g. NAME_SUFFIX=_mpi

Added new make target: clean_intermediates

* Added "verifiable", a suite of kernels for generating and verifying reduction
  input and output arrays in a bit-precise way.
* Data corruption errors now reported in number of wrong elements instead of max
  deviation.
* Use ncclGetLastError.
* Don't run hypercube on non-powers of 2 ranks.
* Fix to hypercube data verification.
* Use "thread local" as the defaut CUDA capture mode.
* Replaced pthread_yield -> sched_yield()
* Bugfix to the cpu-side barrier/allreduce implementations.
