Hi,
this patch should avoid production of RTL only for those vars that we know are
never used by real code.

Here we die because we do not have variable constructor in LTO stream because
the variable was optimized out at compile time already. Do we still need to
build RTL here? We can easily check for optimized out

But if we need a placeholder RTL, I suppose most practical variant would be

When this code is invoked, DECL_RTL for some variable might not be set yet,
even when it will or might be set later on (e.g. TLS vars), e.g. when compiling
some other function.
So, we need some RTL for it but

was optimized out...
It does not make sense to try to figure out section of
