Andi Kleen d73bad0685 perf tools: Expression parser enhancements for metrics 
Enhance the expression parser for more complex metric formulas.

- Support python style IF ELSE operators
- Add an #SMT_On magic variable for formulas that depend on the SMT
status.

Example: 4 *( CPU_CLK_UNHALTED.THREAD_ANY / 2 ) if #SMT_on else cycles

- Support MIN/MAX operations

Example: min(1 , IDQ.MITE_UOPS / ( UPI * 16 * ( ICACHE.HIT + ICACHE.MISSES ) / 4.0 ) )

This is useful to fix up problems caused by multiplexing.

- Support | & ^ operators
- Minor cleanups and fixes
- Support an \ escape for operators. This allows to specify event names
like c2-residency
- Support @ as an alternative for / to be able to specify pmus without
conflicts with operators (like msr/tsc/ as msr@tsc@)

Example: (cstate_core@c3\\-residency@ / msr@tsc@) * 100
