JDK-8067014 - LinearScan::is_sorted significantly slows down fastdebug builds' performance
Description
compiler/codegen/8001183/TestCharVect.java test times out in fastdebug builds, due to overwhelming asserts. On my very fast dev Linux x86_64 4.0 GHz desktop with latest jdk9-dev/fastdebug: 

compiler/codegen/8001183/TestCharVect.java: 
.... 
Timeout signalled after 400 seconds

Test profile shows unequivocally to LinearScan::is_sorted and RangeCheckEliminator::Verification::can_reach:
