[libcxx] [test] Don't look for the literal spelling __mbstate_t

Authored by mstorsjo on May 28 2021, 4:22 AM.



While the code uses the type name std::mbstate_t, the warning message
mentions the original underlying type, which is a C library internal
type name.

On Windows this type is called _Mbstatet instead of __mbstate_t. Use
expect-warning-re to avoid spelling out the literal name of the type.

Due to issues with the detection of the clang-verify feature, these
tests have been skipped in the Windows CI configuration so far.

LGTM, modulo the remark.


I think it would be good to add some comment like "Don't test for the exact type since the underlying type of std::mbstate_t depends on implementation details."
