[libcxx] r254050 - Silence a -Wmissing-braces warning in the tests; mbstate_t is defined differently on different C libraries.

[David Blaikie via cfe-commits]

Could this initialization just be written as "mbstate_t mb = {}" & avoid
the warning entirely (I'm not entirely sure what the warning was, but I
imagine that'd avoid it)
