Only LTRANS should be affected - WPA definitely does not need any of this
(rest_of_decl_compilation). LTRANS OTOH does not need any type / symtab
merging. Merged WPA/LTRANS phase of course complicates things here.
What I can't see is why this all should make a difference at LTRANS?
Do we garbage-collect unused globals there before wrapping up global decls?
Do we somehow not ship them to the correct LTRANS units?
We'd wanted to get rid of lto_global_var_decls orginally (replace it by
symtab). At the moment it's _only_ used for calling rest_of_decl_compilation
on globals (and for static we call that twice ...). So, HJ, your patch does
look reasonable for 4.8 - can you give it proper testing and submit it?
OTOH the LTO path should not call rest_of_decl_compilation but sth more
specific ... (most of it is disabled for the LTO path anyway).
