hv: add compile time assert for static checks Add two files to do compile time assert. One is arch specific, and put in hypervisor/arch/x86/. The other one is common, and put in hypervisor/common/. If the statement is not true, there will be error during compile time. The file will not increase the size of HV binary.

hv: fix a minor bug of static checks When a macro is expanded, the two tokens on either side of each ‘##’ operator are combined into a single token, which then replaces the ‘##’ and the two original tokens in the macro expansion. So we need use CAT__ to expand the __LINE__ MACRO and use CAT_ to combine the expaneded MACRO.
