Profiling with compiler

[myurkin]

ADDA contains detailed timing in log files. Still, it is a pity that users rarely (if at all) use standard profiling of the code provided by any compiler. In principle, one can modify the Makefile to enable profiling and some people did that.

The goal of this issue is to play with this option and to implement a Makefile option for it (to make it easier to use and conform to other compilation options set in Makefile). Another goal is to adjust Eclipse configurations to make profiling with as few clicks as possible.

If successful, this can replace cumbersome PRECISE_TIMING.
