Wei Zhang 0f173234bb Add -L$(MPI_HOME)/lib64 to NVLDFLAGS
In some cases, the MPI library is not in $(MPI_HOME)/lib but
in $(MPI_HOME)/lib64. For example, on RedHat like Linux system
(CentOS, Amazon Linux), and MPI is installed by yum or rpm.

Under such circumstance, the current make file will cause failure.
This patch address this issue by adding -L$(MPI_HOME)/lib64 to
NVLDFLAGS in src/Makefile.

David Addison cbe7f65400 Resync all tests with test code from NCCL 2.4
Major rework to merge most of the changes from the NCCL internal
tests into the public ones

Added "-m <agg_iters>" operation aggregation option.
Data integrity checking is now much more performant at scale.
Startup times at scale are improved.
Test latency units are now displayed in usec.
