> This task aims to fix the following miscellaneous issues of worst-case and parfor memory
estimates: 
> 1) Incorrect handling of incomplete worst-case estimates (can result in negative memory
estimates)
> 2) Incorrect parfor estimates of operations with spark execution type (handled as forced
execution type)
> 3) Incorrect parfor estimates in case of constrained optimizer with unspecified degree
of parallelism and/or execution type.
