Allow HLT_PFJet260 back in the GRun table (PS=0), for validation purposes
Updated to C++11 recommended style

Added override and switched using for typedef
Fixed clang compiler error

Removed incorrect use of typename. This change also works fine for gcc.
Removed unused member data

The clang compiler was warning about member data which were never
used.
Silence warning about hiding a virtual function

The clang compiler issued a warning that the declaration of result(...)
hid the version of that function from the base class. As the new
result(...) was being used and therefore was intended to be different from
the base class, issuing a 'using' declaration for the base class function
now silences the warning.
Fixed clang compiler warnings and errors

Fixed unused member data warnings.
Fixed invalid use of 'd' to declare a double.

chrono: improvements to IFUNC and native timers

  - check for GCC >= 4.6 (not only GLIBC >= 2.11.2) before using IFUNC
  - implement native IFUNC-based timer
  - implement fall-back mechanism when IFUNC is not available
  - clean up native TSC timers
