        * calls.c (gimple_maybe_alloca_call_p): New function.  Return true
        if STMT may be an alloca call.
        (gimple_alloca_call_p, alloca_call_p): Return only true for the
        builtin alloca call.
        * calls.h (gimple_maybe_alloca_call_p): New function.
        * tree-inline.c (inline_forbidden_p_stmt): Use
        gimple_maybe_alloca_call_p here.
