[LLVMdev] Create "appending" section that can be partially dead stripped
...ine when processed with full optimisations. That's of course no proof
that there won't be any problems in any case.
However, I'm not sure how to add a symbol without data at the start
and end of the section. Adding a [i32 x 0]-typed symbol still inserts
a byte (see the @arrstart/@arrstop). I can't work with alias
declarations to the first and last element, since then the first and
last element will always be considered live.

Thanks for the suggestion, but it still puts everything in a single
.section statement.
