The test is not applicable because HWASan does not intercept __tls_get_addr.
This is pre-emptive cleanup, to get ready for Kirill's patch to enable sanitizer common tests for HWASan (https://reviews.llvm.org/D147067).
Note that there is an outstanding dynamic TLS bug for sanitizers - https://github.com/google/sanitizers/issues/1409
- but that isn't applicable here due to the lack of interception.
Test: LIT_FILTER=resize_tls_dynamic ninja check-sanitizer
it should be XFAIL for HWASAN, as we likely will intercept this for HWASAN
