[Bug c++/39236] New: G++ sets TREE_STATIC and DECL_EXTERNAL on the same VAR_DECLs

[jason at gcc dot gnu dot org]

G++ uses TREE_STATIC to mean "will be written out statically somewhere" rather
than "write out statically in this TU"; it should be set on VAR_DECLs that also
have DECL_EXTERNAL set.

Historically we've set DECL_EXTERNAL on anything that we weren't yet sure
whether or not we were going to write out in the current TU in order to support
assemble_external; now that we are always in unit-at-a-time mode that isn't
necessary anymore, so we can do away with the DECL_NOT_REALLY_EXTERN trickery.

Confirmed, I had saw this originally when I was doing the store-ccp patch which
optimized static constant variables that just happened not to be initialized.
