Function LLVMGetRawDataValues 

pub unsafe extern "C" fn LLVMGetRawDataValues(
    c: LLVMValueRef,
    SizeInBytes: usize,
) -> *const c_char

Get the raw, underlying bytes of the given constant data sequential.

This is the same as LLVMGetAsString except it works for all constant data sequentials, not just i8 arrays.
