The previous test incorrectly assumed 32-bit integers, leading to incorrect bit
counts. This change updates the test result to assume 64-bit integers.

Subject: [PATCH] [clang][x86] Fix `_mm512_popcnt_epi64` constexpr test
The previous test incorrectly assumed 32-bit integers, leading to
incorrect bit counts. This change updates the test result to assume
64-bit integers.
