The common profile usage is to collect profile from a target and then use the profile to guide the optimized build for the same target dedicatedly. There are some cases that no profile can be collected for a target. In those cases, although no dedicated profile is available, it is possible to have some generic profile to optimize common libraries and utilities. A flag is needed to tell the non-dedicated profile from the dedicated profile apart, so compiler can use different strategy for them.
