RFR: 8257420: Zero VM build broken with clang after JDK-8256726 due to strlen() is not a constexpr

[Jie Fu]

Hi all,

The newly added STATIC_ASSERT [1] breaks the build of Zero VM with clang.
It complains that 'non-type template argument is not a constant expression' since strlen() [2] is not a constexpr.

Any comments?

Thanks.
Best regards,
Jie
