Transfered from https://issues.dlang.org/show_bug.cgi?id=20572

Description

It would be helpful if the ProcessException thrown by spawnProcess also included the process name.  So instead of:

Failed to spawn new process (The system cannot find the file specified.)

This message would be more helpful:

Failed to spawn process 'SOMEPROGRAM' (The system cannot find the file specified.)
