Frontend,Backend: add xxtvala support
* utils
* Add checkInputWidth function in NamedUInt to check if the UInt arg passed in has the same width as it defined.
* Frontend
* Pass the unexpanded instruciton to IBuffer if the C extension 16 bits instruction is illegal.
* No need to use bypass illBuf, since the origin 16 bits instruction will be passed in the ctrlflow bundle.
* IBuffer
* Merge exceptionType and crossPageIPFFix into 3bit field, which type is IBufferExceptionType.
* IBufferExceptionType can hold illegal instruction exception.
* Backend
* CSROpType.ro is removed, since we can use rs1 and rd passed in imm field to distinguish CSRR and CSRW in CSR module.
* Create TrapInstMod to store the trap instruction and handle its update.
