* Fix hipMemcpy-size test running out of Host Mem The hipMemcpy-size uses a maxElem calculated from the total GPU mem /8. Then it will allocate 4 times that amount of host memory. This tests begins failing when there is not enough host memory, such as on systems with 32GB GPU mem, and 16GB RAM. This fixes the test if not enough host memory is available on the system. * Add windows support to hipMemcpy-size fix * avoid linking extra libs for windows * HIPMemcpy-size Remove freeCPU including swap
