RFR: 8151440: Move BitMap verfication inline functions out from bitMap.hpp

[Stefan Karlsson]

Hi all,

Please review to fix include problems with the bitMap files.

http://cr.openjdk.java.net/~stefank/8151440/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8151440

Some verification code in bitMap.inline.hpp is used from bitMap.hpp. 
This adds a requirement that bitMap.inline.hpp always have to be 
included when bitMap.hpp is included, otherwise the compiler will complain.

The patch fixes this by moving the verification/debugging code to the 
cpp file, and the move some inlined functions from bitMap.hpp to 
bitMap.inline.hpp.

Thanks,
StefanK
