[Bug debug/42800] [4.5 Regression] VLA DW_AT_upper_bound is no longer emitted

Yes.  This is -O0, so we definitely should ensure that the debug info has the
correct upper bound.
Look at gimplify_type_sizes which for -O0 clears DECL_IGNORED_P on the
temporaries to make sure they are not optimized out.  That worked well in 4.4,
but probably doesn't work any longer.
