[PATCH 0/2] Add C-SKY support

Mon Apr 1 02:33:00 GMT 2019

Hi,
This patch add backend support for C-SKY architecture.
Tested on X86 and got no regression.
Also tested on C-SKY qemu. I didn't find any easy way to do the cross test,
so I modified the test script to run the test suite with ssh, some testcases
fail due to the script modification.
