RFR: 8264868: Reduce inclusion of registerMap.hpp and register.hpp [v2]

[Ioi Lam]

> Register.hpp is included 815 times, and registerMap.hpp is include 862 times (out of about 1000 HotSpot .o files).
> 
> This can be reduced by refactoring the popular header file **frame.hpp**, so that it doesn't include registerMap.hpp anymore. This reduces the number of .o files that include register.hpp to 612, and that of registerMap.hpp to 109.
> 
> The total number of lines of C++ code compiled for HotSpot is reduced by about 0.5%.
