Fix gcc.dg/attr-alwaysinline.c

[Jan Hubicka]

Hi,
this is regression introduced by my earlier patch to avoid unused static
functions to be optimized out.

Sorry for that, I must've missed the regression in my testing originally.

Also perhaps little discussion should go into whether we want the normal
inline functions to be output and what to do about static variables.  At
the moment we force all inline functions to be output and we optimize
out all unused statics at -O0 (we didn't do that in pre-cgraph world).
Both cases are easy to fix if there is reason for doing so.  (in fact I
already tested patch).

Boostrapped/regtested i686-pc-gnu-linux, will commit it shortly.
