target/i386: fix INHIBIT_IRQ/TF/RF handling for PAUSE

PAUSE uses DISAS_NORETURN because the corresponding helper
calls cpu_loop_exit().  However, while HLT clear HF_INHIBIT_IRQ_MASK
to correctly handle "STI; HLT", the same is missing from PAUSE.
And also gen_eob() clears HF_RF_MASK and synthesizes a #DB exception
if single-step is active; none of this is done by HLT and PAUSE.
Start fixing PAUSE, HLT will follow.
