perf annotate browser: Make feature toggles global
Browse files Browse the repository at this point in the history 
So that when navigating to another function from a call site or when
going to another annotation browser thru the main report/top browser the
options (hide source code, jump arrows, jumpy lines, etc) remains the
last ones selected.
