Thanks, Dave!

These patches passed GLIBC built-in tests and more tests HJ and I put together
at https://github.com/hjl-tools/cet-smoke-test.

I made some changes since V3 as outlined in the cover letter.
In particular there are two new patches for the VMA guard and preventing shadow
stack merging.  Does anyone have comments on those and the whole Shadow
Stack/IBT series in general?

Thanks,
Yu-cheng
