[8u60] request for review: 8068489: remove unnecessary complexity in Flow and Bits, after JDK-8064857

[Vicente-Arturo Romero-Zaldivar]

Hi,

Please review the backport of bug:

8068489: remove unnecessary complexity in Flow and Bits, after JDK-8064857

JDK9 bug: https://bugs.openjdk.java.net/browse/JDK-8068489
backport: https://bugs.openjdk.java.net/browse/JDK-8068547
original patch pushed to 9: 
http://hg.openjdk.java.net/jdk9/jdk9/langtools/rev/5e500700b168
public review: http://cr.openjdk.java.net/~vromero/8068489/webrev/

The original patch doesn't apply cleanly. There are no major differences 
but I think that there are enough to deserve a review.

Thanks,
Vicente
