How to use licm.disable loop attr metadata in c++

[zzzhhhl]

[RISCV] In this commit, we can use llvm.licm.disable to disable licm in 4f64f1b.
BUT, it seems there is no way to add metadata in cpp.

I code like #pragma clang loop vectoriaze(disable), #pragma licm(disable), it doesn't works.

Clang does not currently support this pragma. "llvm.licm.disable" is just the compiler internal metadata.

Is there any plans to supports this in future? It looks some useful to some target like riscv vector extension.
