[llvm] [msan][NFCI] Rename tests and update comment (PR #127926)

[Thurston Dang via llvm-commits]

https://github.com/thurstond created https://github.com/llvm/llvm-project/pull/127926

This renames the neon_* tests to be more consistent with the original file that they were forked from.

It also fixes the header comment for llvm/test/Instrumentation/MemorySanitizer/AArch64/arm64-vcvt.ll (instrumentation was updated in #126136 aka e9e6ba6a5e2a4ca7386861136196903febb9968b, but the comment was not).
