Memory exhausted when elaborating Verilog netlist

[Blebowski]

This is follow-up of trying to elaborate Verilog netlist from #1333.

When I set the -H parameters and -M parameters to 2048m, the NVC tries to elaborate the
netlist for some time until it exhausts all the memory.

I tried on 20 GB virtual machine and 64 GB notebook with Intel 12900H, the result is the same.
I ran it through Valgrind (I aborted the execution after some time), see the log attached:

macandd_log.txt

Also, I was surprised to see that the -M option has no effect here. Looking through the codebase
I see that using xcalloc, xmalloc, etc. has nothing to do with this, the -M is used to track only
the arena allocator to represent the object_t data structures.

IMHO it would be more user friendly if the meaning of the -M option was:
"Maximal memory single NVC process can consume",
and be bumped to sth. like 2GB by default.
