[DeLICM] Fix unused zone for writes without in-between read.
The implementation of computeArrayUnused did not consider writes without
reads before, except for the first write in the SCoP. This caused it to
'forget' writes directly following another write.
This patch re-adds the entire reaching defintion of a write that has not
been covered before by a read.
This fixes Polybench 4.2 2mm where only one of the matrix-multiplication
was detected.
