The PR #16465 exposes a PackedFunc wrapper for Python's regex matching. The limited functionality it has, checking for a match without returning any extracted results, is sufficient for all existing uses of |

Currently, the pytorch wheels available through `pip install` use the pre-C++11 ABI by setting `-DUSE_CXX11_ABI=0` [0]. If TVM were to user the pre-C++11 ABI, this would cause breakages with dynamically-linked LLVM environments. This commit adds a lint check to search for use of `#include <regex>` in any C++ files. Use of this header should be avoided, as its implementation is not supported by gcc's dual ABI. This ABI incompatibility results in runtime errors either when `std::regex` is called from TVM, or when `std::regex` is called from pytorch, depending on which library was loaded first. This restriction can be removed when a version of pytorch compiled using `-DUSE_CXX11_ABI=1` is available from PyPI. [0] pytorch/pytorch#51039
