Code Change:
1) PeiMain module use PeiCoreEntryPoint library class but *not* original OldPeiCoreEntryPoint.
2) The memory service in PeiMain module get CAR base and size from parameter of PeiCore's
2) The memory service in PeiMain module get temporary memory base and size from parameter of PeiCore's
Entry point directly but *not* computed from stack's base.
Possible Impacts:
