Support SameTebFlags.InitialThread

Browse Source 
This flag is needed to suport emulation of .net executables
that don't have an entry point set in PE header. This applies
to both PE32 and PE64 executables. If InitialThread is set
the loader substitutes an entry point of the .net executable
with mscoree.dll!_CorExeMain.
