LLVM santizers and GDB regression test suite.

As NetBSD-9 is branched, I have been asked to finish the LLVM sanitizer integration. This work is now accomplished and with MKLLVM=yes build option (by default off), the distribution will be populated with LLVM files for ASan, TSan, MSan, UBSan, libFuzzer, SafeStack and XRay.

I have also transplanted basesystem GDB patched to my GDB repository and managed to run the GDB regression test-suite.

• NetBSD distribution changes

I have enhanced and imported my local MKSANITIZER code that makes whole distribution sanitization possible. Few real bugs were fixed and a number of patches were newly written to reflect the current NetBSD sources state. I have also merged another chunk of the fruits of the GSoC-2018 project with fuzzing the userland (by plusun@).
