stress-ng V0.18.11 "optimized OS oppressor"

This release comes with several hundred branch hints for improved
if/else branching, many bug fixes and porting improvements. Also
a new mmaptoture stressor has been added to hammer page related
system calls.

New Stressors

• mmaptorture - memory mapping torture stressor

New Options

• --intmath-fast - use fast integer types for intmath stressor
• --pci-ops-rate - throttle PCI stressor bogo-ops rate
