MAIN:ragge:20110707075106 created by ragge on 07 July 2011, 09:51:06 +0200 (3 years ago) (patch) Check for (x-y)+z where all vars are pointers to the same struct,
and remove the unneccessary mul/div. This has two advantages:
- Remove unneccessary mul+div.
- Give correct result even if some of the variables points to
unaligned structs. People may get surprised otherwise.
This fixes Jira#PCC-355 by Iain Hibbert.
