RegexValidator needs support for flags passed to `re.compile` (migrations do not allow for compiled patterns)

When using a RegexValidator with a compiled pattern, makemigration fails:
ValueError: Cannot serialize: <_sre.SRE_Pattern object at 0x24e8ac0>
A sample model:
from django.core.validators import RegexValidator pattern = re.compile(r'foo', re.IGNORECASE) validator = RegexValidator(pattern) class Model(models.Model): foo = models.CharField( validators = [validator], ... )
This is somehow expected, and when passing in the pattern uncompiled it works.
But this won't allow to use re.IGNORE_CASE or other flags for re.compile anymore.
RegexValidator should support a new argument flags, which would then be used for non-compiled patterns (passed on to re.compile).
Let me know, if I could provide a pull request / patch for this (as far as I can see) trivial change.
(It seems like with the new migrations, supporting a pre-compiled pattern is not really relevant anymore (but could be kept still))
