Reduce a memory usage for ABO V1.2

Issue summary:
Spending a huge memory usage by ABO V1.2.

Details:
This customer which has been testing ABO V1.2 from 1Q/2017 faces to remarkably run short of memory. (e.g. it's needed 5GB memory for 650k OFFSET size.)
There is a possibility that will happen in not testing environment but also production one.
It's quit difficult to add on other real storage or AUX one due to performance reasons.

Our request:
Fix this problem until 12/2017 in order to start their project on time.
As I expect, it needs to reduce of memory or replace it to disk storage like a SORT work.
If it couldn't be resolved, more and more customer will claim it critically, so support it ASAP.

    IBM has accepted this RFE to work on reducing the memory required when running ABO.

    ABO 1.3 already provides significant reductions in the memory used relative to ABO 1.2

    The goal of this RFE is to continue to reduce the memory required by ABO 1.3, particularly for large modules. However it should be noted that ABO will always require more memory than older versions of COBOL compilers. This is because ABO itself is a 64-bit application so it requires memory above the 2 GB BAR and that the analysis and advanced optimizations done by ABO require substantial machine resources. It can be expected that some large modules or modules containing a large number of CSECTs will require up to 10GB in memory to be optimized by ABO.

    There must be enough memory allocated to each ABO invocation, via REGION and MEMLIMIT settings, for ABO to operate. Too little memory will result in ABO issuing error messages and/or ABO taking a long time to complete optimization due to excessive memory paging. This means that you may need to limit the number of parallel invocations of ABO if the memory resources of the machine are limited.

    Please see documentation in the ABO User's Guide for more details on ABO memory usage and the recommended settings for REGION and MEMLIMIT when running ABO. https://www.ibm.com/support/knowledgecenter/SSERQD_1.3.0/com.ibm.opt.doc/ug/recomset.html
