RFR (S): CODETOOLS-7902344: short-circuit boolean evaluation in @requires expressions

[Boris Ulasevich]

Hello,

Please review this change to introduce short-circuit boolean expressions 
evaluation:

http://bugs.openjdk.java.net/browse/CODETOOLS-7902344
http://cr.openjdk.java.net/~bulasevich/CODETOOLS-7902344/webrev.01

Short-circuit boolean evaluation in @requires expressions helps to avoid 
expression evaluation errors when the VM option is not defined for the 
particular VM build. We use workaround "boolOpt64Bit == true" now while 
we believe the correct expression would be "vm.bits == 64 & boolOpt64Bit".

thanks,
Boris
