This adds an additional column with percentages to the output of
bytecode_dispatch_report.py --top-dispatches-for-bytecode.
The percentages always represent the relative number of dispatches to
the target bytecode to all dispatches from the source bytecode.
The additional flag --sort-sources-relative/-r allows sorting the
"Top sources of dispatches to" the given bytecode by this column to more
easily find bytecodes that significantly often dispatch to the target.

With this patch, every node in turbo-*.json has an opcode, a title, and
a label. The label field is new; the opcode and title were already
there. The title is for the mouseover text. The label is what will be
displayed in the graph view, unless it's too long, in which case only
the opcode will be displayed. (This is similar to the preexisting
behaviour of putting titles in labels, except that the titles were
rarely short enough to fit in a label.)
With this patch, the labels generated are in practice the same as the
titles we had before, except for LoadField and StoreField, which will be
rendered as LoadField[[+432]] and StoreField[[+432]] (if 432 was the
offset).
This diff adds an overloadable method
virtual void Operator1<T>::PrintParameter(ostream&, PrintVerbosity)
for each type T to Operator1. Its default implementation just uses
operator<<(ostream&, T const&) and adds square brackets around it, but
it is overridden for FieldAccess to print "[+432]" in the example case.

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.

Since Linux 4.1, flag -f became -F, but the long option --flags stayed
the same. Using --flags assures compatibility with new and old versions.
Also, symbols appear to be reported as name+offset in newer versions
even when not requested, so we trim the latter part if present.

This version of the isolate_driver includes a feature
that automatically derives shared libraries for inclusion.
This is needed for GN as the shared library location is
different compared to gyp and having different configs
would be tedious.
This also removes the shared-library-specific configs as
they are no longer needed with the new driver.

Having presubmit called from within the test runner often
requires logic to remove the call again.
After the GN transition it would be better if presubmit is
called by a wrapper script if needed at all. It is run

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.

This makes the isolate-driver script rebase all paths to be

of the go binaries and is needed for batcharchive to work.
