Use an initial shared memory size of 256 GB on Apple.
This implements an idea that Nicolas had to overcome the Darwin
problem that it is not possible to extend a shared memory segment
on that system.
The remedy is simple: Use a memory segment that is larger than
what can reasonably be used. This should only waste a few page
table entries, while providing the functionality, at least for
further testing.
libgfortran/ChangeLog:
* caf_shared/shared_memory.c (shared_memory_init): On Apple,
use an initial size of 256 GB.
