perf tools: Add parser generator for events parsing
Changing event parsing to use flex/bison parse generator. The event syntax stays as it was. grammar description: events: events ',' event | event event: event_def PE_MODIFIER_EVENT | event_def event_def: event_legacy_symbol sep_dc | event_legacy_cache sep_dc | event_legacy_breakpoint sep_dc | event_legacy_tracepoint sep_dc | event_legacy_numeric sep_dc | event_legacy_raw sep_dc event_legacy_symbol: PE_NAME_SYM event_legacy_cache: PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT '-' PE_NAME_CACHE_OP_RESULT | PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT | PE_NAME_CACHE_TYPE event_legacy_raw: PE_SEP_RAW PE_VALUE event_legacy_numeric: PE_VALUE ':' PE_VALUE event_legacy_breakpoint: PE_SEP_BP ':' PE_VALUE ':' PE_MODIFIER_BP event_breakpoint_type: PE_MODIFIER_BPTYPE | empty PE_NAME_SYM: cpu-cycles|cycles | stalled-cycles-frontend|idle-cycles-frontend | stalled-cycles-backend|idle-cycles-backend | instructions | cache-references | cache-misses | branch-instructions|branches | branch-misses | bus-cycles | cpu-clock | task-clock | page-faults|faults | minor-faults | major-faults | context-switches|cs | cpu-migrations|migrations | alignment-faults | emulation-faults PE_NAME_CACHE_TYPE: L1-dcache|l1-d|l1d|L1-data | L1-icache|l1-i|l1i|L1-instruction | LLC|L2 | dTLB|d-tlb|Data-TLB | iTLB|i-tlb|Instruction-TLB | branch|branches|bpu|btb|bpc | node PE_NAME_CACHE_OP_RESULT: load|loads|read | store|stores|write | prefetch|prefetches | speculative-read|speculative-load | refs|Reference|ops|access | misses|miss PE_MODIFIER_EVENT: [ukhp]{0,5} PE_MODIFIER_BP: [rwx] PE_SEP_BP: 'mem' PE_SEP_RAW: 'r' sep_dc: ':' | Added flex/bison files for event grammar parsing. The generated parser is part of the patch. Added makefile rule 'event-parser' to generate the parser code out of the bison/flex sources.
