Localizing dates to a timezone with dls after 2038 does not work (2038 Problem)
#### Code Sample, a copy-pastable example if possible

```python
pandas version 0.24.2

dates = pd.date_range(start='1/1/2037 00:00:00', end='12/31/2038 23:00:00', freq='h')
test = pd.to_datetime(dates, infer_datetime_format=True)
test = test.tz_localize('Etc/GMT+8').tz_convert('America/Los_Angeles')

```
#### Problem description

[Current behavior correctly dls corrects years before 2038.  It is necessary for forecasting applications (and other applications) to have dls corrections after 2038]

**Note**: Many problems can be resolved by simply upgrading `pandas` to the latest version. Before submitting, please check if that solution works for you. If possible, you may want to check if `master` addresses this issue, but that is not necessary.

For documentation-related issues, you can check the latest versions of the docs on `master` here:
