RFR: 8200232: Build failures after JDK-8200106 (Move NoSafepointVerifier out from gcLocker.hpp)

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8200232

Webrev:
  http://cr.openjdk.java.net/~shade/8200232/webrev.01/

Testing: x86_32 build

I only saw failures on x86_32, but maybe PPC folks see the breakage in other configs too?

Thanks,
-Aleksey
