RFR: 8358641: C1 option -XX:+TimeEachLinearScan is broken

[Saranya Natarajan]

**Issue** 
Using the command` java -Xcomp -XX:TieredStopAtLevel=1 -XX:+TimeEachLinearScan` results in an assert failure in line `assert(_cached_blocks.length() == ir()->linear_scan_order()->length()) failed: invalid cached block list`.

**Suggestion**
Removal of flag as this is a very old issue 

**Fix**
Removed the flag by removing relevant methods and code while ensuring the removal does not affect other flags.
