Hi,
this makes fold_unary_loc fold NON_LVALUE_EXPR if the argument cannot be a
lvalue (this happens when you're re-fold-building an existing tree) and
changes the first call to fold_convert_const to use arg0 instead of op0, like
the other 2 calls just below (this should not change anything if the argument
is correctly folded, but is more forgiving if it is not).
Tested on x86_64-suse-linux, OK for the mainline?

Seems reasonable. Do you happen to have a testcase where you can see
the effects in one of the dumps?
