[PATCH 0/1] Add Zihintpause support

[Dao Lu]

This patch adds RISC-V Zihintpause support. The extension is set to be enabled
by default and opcode has been added to insn32.decode.

Added trans_pause for TCG to mainly be a no-op and break reservation.

The change can also be found in:
https://github.com/dlu42/qemu/tree/zihintpause_support_v1

Tested along with pause support added to cpu_relax function for linux, the
changes I made to linux to test can be found here:
