This is the third iteration of the C-SKY port patch set. The previous
versions were posted here:

https://gcc.gnu.org/ml/gcc-patches/2018-07/msg01861.html
Changes since V2 are:
- The cse_cc pass is gone, replaced by a no-op move of the cc register
to allow the regular CSE pass to work.
- The backend defines the new TARGET_HAVE_SPECULATION_SAFE_VALUE hook
(this architecture isn't affected by speculative-execution bugs).
Same 5 pieces in the series as before:
[1] Configury
[2] Backend implementation
[3] Documentation
[4] Testsuite
[5] libgcc
