include: Extend get_insn() to read instruction from VS/VU mode

Browse Source 
Current implementation of get_insn() is not suitable for reading
instruction from VS/VU mode because we have to set SSTATUS_MXR bit
in VSSTATUS CSR for reading instruction from VS/VU mode.

This patch extends get_insn() to read instruction from VS/VU mode.
