Summary

Change the C1 JIT compiler flag "TimeLinearScan" from product to develop.

Problem

This flag is only used in code guarded by "#ifndef PRODUCT"

Solution

Make the flag a develop flag.

Specification

-  product(bool, TimeLinearScan, false,                                      \
+  develop(bool, TimeLinearScan, false,                                      \
           "detailed timing of LinearScan phases")                           \
