TargetPassConfig: Move addPass of IPRA RegUsageInfoProp down.

Browse Source 
TargetPassConfig::addMachinePasses() does some housekeeping first:
Handling the -print-machineinstrs flag and doing an initial printing
"After Instruction Selection". There is no reason for RegUsageInfoProp
to run before those two steps.
