perf annotate: Use a hashmap to save type data
It can slowdown annotation browser if objdump is processing large DWARF
data. Let's add a hashmap to save the data type info for each line.
Note that this is needed for TUI only because stdio only processes each
line once. TUI will display the same line whenever it refreshes the
screen.
