Internal error when disk size is too small during compilation

[meisterT]

If we run out of disk space during compilation (think about test-memstatic.cc, we create an internal error which does not have any useful information.

We should try to check whether we have enough space ahead of time and even if we miscalculate, we should have some useful info in the internal error.

How can we reasonably calculate the required space ahead of time?

There is script_filesize_limit?
