[jdk25u] RFR: 8367333: C2: Vector math operation intrinsification failure

[Aleksey Shipilev]

Avoids the `fatal` VM crash when using Vector code. Fixes recent regression in JDK 25.

Additional testing:
 - [x] New test fails (crashes VM) without the fix in both release and fastdebug modes, works with the fix
 - [ ] Linux x86_64 server fastdebug, `all`
