[PATCH V11 12/15] perf tools: add missing 'abi' member to 'struct regs_dump'

[Adrian Hunter <adrian.hunter@intel.com>]

And store the parsed value there.  Note that the 'abi' is
0 (no registers), 1 (32-bit registers) or 2 (64-bit registers),
but the registers are anyway copied one-by-one as 64-bit
values onto the event i.e. see 'perf_output_sample_regs()'
