Set PROP_gimple_lva for functions without IFN_VA_ARG
2015-04-17 Tom de Vries <tom@codesourcery.com>
* gimplify.c (gimplify_function_tree): Tentatively set PROP_gimple_lva
in cfun->curr_properties.
(gimplify_va_arg_expr): Clear PROP_gimple_lva in cfun->curr_properties
if we generate an IFN_VA_ARG.
* tree-inline.c (expand_call_inline): Reset PROP_gimple_lva in dest
function if PROP_gimple_lva is not set in src function.
