RFR(XS): 8245521: Remove STACK_BIAS

[Mikael Vidstedt]

Please review this small change which removes the STACK_BIAS constant and its uses:

JBS: https://bugs.openjdk.java.net/browse/JDK-8245521
webrev: http://cr.openjdk.java.net/~mikael/webrevs/8245521/webrev.00/open/webrev/

Background (from JBS):

With Solaris/SPARC removed the STACK_BIAS definition in src/hotspot/share/utilities/globalDefinitions.hpp is now always 0 and can be removed.


Testing:

Tier1

Cheers,
Mikael
