All events recorded are shown in separate columns simulatneously, using
rectangles with heatmap-style colouring. Hovering over the shapes gives
the event name, count, and percentage.

Also convert CodeView to a class and fix a host of selection
bugs in the process, as well as move the logic and data to
"enrich" location with one type of location data with location
data known globally to the whole graph in the selection broker.

perf-turbo.py merges a perf data file and a turbofan trace file into a
single json object which can then be piped to a file and uploaded to
turbolizer to display the profiling data in the disassembly. With the
changes, turbolizer now shows the event counts for instruction in
percentage form and with heatmap-stype colouring. Multiple different
events can be recorded at once with a new drop-down menu to select which
event to view the counts of. The documentation has been updated with
instructions. Using the script is optional and turbolizer retains
previous functionality if a trace without profiling data is uploaded.

This change analyzes and links the output of --code-comments in the disassembly view within turbolizer with the other views, such that selecting these comments will also select the respective blocks/lines/nodes within the other views. The block start comments (e.g. -- B4 start --) are linked with the blocks in the schedule phase view and vice versa. The source position comments (e.g. -- primes.js:3:10 --) select the respective spans, lines, and nodes in the JavaScript code view, the schedule phase view, and the other compilation phase views respectively, and vice versa. It also modifies the display of the line and column numbers in the source position comments to be offset from 1 instead of 0 and ignore the initial source position of the first line of code (from removal of the function name in the compiler).
Also fixed the bug where previous selections weren't being cleared properly across multiple views, adding appropriate clear calls when using the selection broker.

Fix bugs and add a few small useful features:
* Fix Schedule view to properly parse schedule output and respond to switching
back to graph views.
* Add shorcuts for showing edges of selected nodes.
- 'i' shows all inputs
- 'o' shows all outputs
- '1'-'9' shows all nodes nth input where 1 <= n <= 9
- 'c' shows all control inputs
- 'e' shows all effect inputs
* Holding the control key down when using a edge-showing shortcut toggles edge
state rather the just showing.
* 'a' selects all nodes in graph view.
* Node selection is preserved between graph views and Schedule views.
* Holding control key down when using regular expression search shows currently
hidden nodes that match the regex search.
* Pane expansion buttons now respond to clicks in entire button area.
* Default text in regex search box makes searching more discoverable.
