[PATCH v4 2/4] perf annotate: Create a annotate2 flag in struct symbol

[Jin Yao <yao.jin@linux.intel.com>]

We often use the symbol__annotate2() to annotate a specified symbol.
While annotating may take some time, so in order to avoid annotating
the same symbol repeatedly, the patch creates a new flag to indicate
the symbol has been annotated.
