says that in for-range-declaration only type-specifier or constexpr
can appear. As the following testcases show, we've emitted some
diagnostics in most cases, but not for static/thread_local (the patch
handles __thread too) and register in the non-sb case.
For extern there was an error that it is both extern and has an
initializer (again, non-sb only, sb errors on extern).
The following patch diagnoses those cases with pedwarn.
I've used for-range-declaration in the diagnostics wording (there was
already a case of that for the typedef), so that in the future
we don't need to differentiate it between range for and expansion
statements.
