[PATCH v3 4/7] perf annotate: Add --disassembler command-line option

[Ian Rogers <irogers@google.com>]

Add the --disassembler command-line option to perf annotate. This
allows users to explicitly request or override the disassembler
preferences (e.g. --disassembler libasm) directly on the command
line.
