Hi,

I've made it wait too much so I'm posting that for review now. This
implements range breakpoints on some AMD machine by extending the length
field.

Any comment?

Thanks.

perf/x86/amd: AMD support for bp_len > HW_BREAKPOINT_LEN_8
perf tools: allow user to specify hardware breakpoint bp_len
perf tools: add hardware breakpoint bp_len test cases
perf/x86: Remove get_hbp_len and replace with bp_len
