Chen Gang fec7daab3d 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).
