target-tilegx: Add several helpers for instructions translation The related instructions are exception, cntlz, cnttz, shufflebytes.

DEF_HELPER_2(exception, noreturn, env, i32)
target-tilegx: Support iret instruction and related special registers EX_CONTEXT_0_0 is used for jumping address, and EX_CONTEXT_0_1 is for INTERRUPT_CRITICAL_SECTION, which should only be 0 or 1 in user mode, or it will cause target SIGILL (and the patch doesn't support system mode).
