This almost replicates cpython behaviour. The big difference is, that the defaults for the start and end arguments are None rather than 0 and MAX_INT64 (or maybe MAX_INT32?!). I wasn't sure where to obtain these values in a platform independent way, but this could probably be changed quite easily.

This fixes a test, where a non-thread safe container is written to
during testing
To reproduce on at least `linux-64` and `osx-arm64` (and probably
others):
```
NUMBA_THREADING_LAYER=workqueue SUBPROC_TEST=1 ./runtests.py -m 32 numba.tests.test_parfors.TestPrangeSpecific.test_tuple_hoisting
```
On `linux-64`, this can be debugged with `gdb`:
```
(gdb) bt
closure____locals______listcomp____v15____v2build__list__0=...) at <string>:4438
(gdb) f 9
closure____locals______listcomp____v15____v2build__list__0=...) at <string>:4438
4438 <string>: No such file or directory.
(gdb) i args
sched = {meminfo = 0x0, parent = 0x0, nitems = 0, itemsize = 0, data = 0x0, shape = {0}, strides = {0}}
closure____locals______listcomp____v15____v2build__list__0 = {meminfo = 0x0, parent = 0x0}
(gdb) f 8
498 mi->data = NRT_Reallocate(mi->data, size);
(gdb) i args
mi = 0x21d1660
size = 2510933856
```
On `osx-arm64` we can use `lldb`:
```
(lldb) run runtests.py -m 32 numba.tests.test_parfors.TestPrangeSpecific.test_tuple_hoisting
