out of bounds exception handling version 01 in prelude.ll
Merge branch 'experimental_backend' of github.com:swp-uebersetzerbau-ss13/fuc into experimental_backend
out of bounds check should be "less than", since arrays are zero indexed
made tests readable again. tip: use in emacs:
  M-x replace-string '\n' '\n"+M-qM-j		           "'
(without the '' signs and with M-q and M-j replaced with the keycodes)
Arrays Out of Bounds checks finished, interaction with structs has to be checked before merging with master
A big merge for lots of local changes regarding arrays...
