We need to construct map for the variable anyway as it might be used
in different SSA names when parameter is set in function.
Do replacement at -O0 for const arguments replaced by constant.
This is important for builtin_constant_p and other construct requiring
constant argument to be visible in inlined function body.
FIXME: This usually kills the last connection in between inlined
function parameter and the actual value in debug info. Can we do
better here? If we just inserted the statement, copy propagation
