c++: Defer emitting inline variables [PR113708]
Inline variables are vague-linkage, and may or may not need to be
emitted in any TU that they are part of, similarly to e.g. template
instantiations.
Currently 'import_export_decl' assumes that inline variables have
already been emitted when it comes to end-of-TU processing, and so
crashes when importing non-trivially-initialised variables from a
module, as they have not yet been finalised.
This patch fixes this by ensuring that inline variables are always
deferred till end-of-TU processing, unifying the behaviour for module
and non-module code.

gcc/cp/ChangeLog:
* decl.cc (make_rtl_for_nonlocal_decl): Defer inline variables.
* decl2.cc (import_export_decl): Support inline variables.

is emitted.
* g++.dg/debug/dwarf2/inline-var-3.C: Likewise.
* g++.dg/modules/init-7_a.H: New test.
* g++.dg/modules/init-7_b.C: New test.
