Currently the header string for different columns in perf report is fixed. Some fields of perf sample could have different meaning for different architectures than the meaning conveyed by the header string. An example is the new field 'var2_w' of perf_sample_weight structure. This is presently captured as 'Local INSTR Latency' in perf mem report. But this could be used to denote a different latency cycle in another architecture. Introduce a weak function arch_perf_header_entry() to set the arch specific header string for the fields which can contain dynamic header. If the architecture do not have this function, fall back to the default header string value.
