[Bug tree-optimization/29484] [4.0/4.1/4.2 Regression] tree-inline.c bug with local static vars

Actually, even C generates one static var for all the inlined functions (in C
within one object), so I'd say we just should mark functions containing
local static variables with &&label in their initializers as non-inlinable,
because anything else means we can't use the same variable for more than
one inlined copy of the function.
In that light the original testcase would just issue an error, as always_inline
function can't be inlined, but e.g.
void baz (unsigned long *);

static inline
void bar (void)
{
  addr:;
  static unsigned long b = (unsigned long) &&addr;
  baz (&b);
}

void
f1 (void)
{
  bar ();
}

void
f2 (void)
{
  bar ();
}
would be a valid testcase that we don't handle properly.
