This is still formally undefined behaviour, but we may as well
keep the *same* undefined behaviour as previous versions.
PEP 796 proposes a cleaner and more consistent replacement for 3.15+
* Whitespaces no longer accepted between `</` and the tag name.
E.g. `</ script>` does not end the script section.
* Vertical tabulation (`\v`) and non-ASCII whitespaces no longer recognized
as whitespaces. The only whitespaces are `\t\n\r\f `.
* Null character (U+0000) no longer ends the tag name.
* Attributes and slashes after the tag name in end tags are now ignored,
instead of terminating after the first `>` in quoted attribute value.
E.g. `</script/foo=">"/>`.
* Multiple slashes and whitespaces between the last attribute and closing `>`
are now ignored in both start and end tags. E.g. `<a foo=bar/ //>`.
* Multiple `=` between attribute name and value are no longer collapsed.
E.g. `<a foo==bar>` produces attribute "foo" with value "=bar".
* Whitespaces between the `=` separator and attribute name or value are no
longer ignored. E.g. `<a foo =bar>` produces two attributes "foo" and
"=bar", both with value None; `<a foo= bar>` produces two attributes:
"foo" with value "" and "bar" with value None.

After Python finalization gets to the point where no other thread
can attach thread state, attempting to acquire a Python lock must hang.
Raise PythonFinalizationError instead of hanging.
This adds a "macro" to the optimizer DSL called "REPLACE_OPCODE_IF_EVALUATES_PURE", which allows automatically constant evaluating a bytecode body if certain inputs have no side effects upon evaluations (such as ints, strings, and floats).
