Increase memory limit for Frama-C (CIL)

Description
Unfortunately it seems that Frama-C (CIL) needs much more memory than previously used CIL. Maybe 1 GB instead of 300 MB will be enough to have the same results. Also we need to increase the default memory limit for deciding verification jobs.

Perhaps, we will not need this if #9538 will shoot.

I did both in branch frama-c-cil. But in one case it did not help. Let's wait for #9538 since too greedy CIL is not good.

One more iteration helped. Unfortunately, Frama-C (CIL) needs very much RAM for merging some source files. At the moment the limit is 2 GB rather than 300 MB as it was for CIL. Job limits start from 3 GB and they are 5 GB even for jobs that have only 2 parallel task generators and one sub-job worker of course. Nevertheless for simple tests one can use much more aggressive parallelism.
After Mikhail made considerable optimizations (#9538) I reduced the CIL memory limit from 2 GB to 1 GB. I didn't change job limits, since specified values seem to be much better.
- Status changed from Resolved to Closed
I merged the branch to master in c082518.
