perf/core improvements and fixes:

Browse source 
- Record min/max LBR cycles (>= skylake) and add 'perf annotate' TUI
   hotkey to show it (c) (Jin Yao)
 
 - Fix machine->kernel_start for PTI on x86 (Adrian Hunter)
 
 - Make machine->env->arch always available, e.g. in 'perf top', not
   just when reading that info from perf.data files (Adrian Hunter)
 
 - Reduce the number of files read at 'perf' start, leaving information such as
   cacheline size, tracefs mount point determination, max_stack, etc, to be
   lazily read as tools needs then (Arnaldo Carvalho de Melo)
 
 - Fixup BPF include and examples install messages (Arnaldo Carvalho de Melo)
 
 - Fixup callchain addresses and symbol offsets in 'perf script', to help
   correlating with objdump output (Sandipan Das)
