// Description:
// file timelegacyapis.cpp
// This executable times how long it takes to call legacy APIs. It should be used when 
// new hardware build targets are introduced. The existing performance tests can then be 
// updated for these platforms.
// Note: The times generated can be used for the following tests:
// - PrintSWVersionAPILegacyTimes					SYSLIB-BAFL-CT-4064
// - PrintLangVersionAPILegacyTimes				SYSLIB-BAFL-CT-4065
// - PrintLangSWVersionAPILegacyTimes				SYSLIB-BAFL-CT-4066
