[Octave-patch-tracker] [patch #10362] Fix problem with trivial ranges in VM

[Markus Mützel]

Follow-up Comment #3, patch #10362 (project octave):

In case this depends on whether an integer is representable as a double
precision number, 2^53 might not be the universal upper limit. IIUC, it can be
larger. E.g., if the base is a multiple of 2^N and the increment is 2^N, the
integers can be represented correctly up to 2^(53+N).

Anyway, the "easy way out" would probably be to just use `octave_idx_type`
here. Afaict, that is `int64_t`. That should be `long` on Linux or `long long`
on Windows.
Imho, correct behavior might be more important than performance in this case.
