Create transactions only if codegen (not rootcling):

Browse Source 
The transactions are useful to buffer Decls before sending them to CodeGen,
to verify semantic validity before emitting. If there is no codegen,
DeclCollecting them wastes CPU cycles during PCH generation time
because all headers are in one single transaction. Of course this also
speeds up regular rootcling invocations.
