This makes test outcomes immutable. This has two benefits:
1) It's more robust. Using the |= operator by mistake
wouldn't lead to unwanted mutation.
2) It's faster as now the set reference can be copied again
when copying test cases. Test case copying happens an order
of magnitude more often than rules do apply.

This adds the possibility to address test cases in the
status file with the variant under which the test is running.
This is only allowed in top-level sections.
Example:
[{
'test-case': [PASS, SLOW],
}]
['variant == foo', {
'test-case': [FAIL],
}]
The test case "test-case" is marked as slow in all variants.
Additionally, in variant foo, it'll be expected to fail.
This CL also exemplifies the new feature with test cases
running under the ignition_turbofan variant. The
corresponding legacy flag is deprecated.

This introduces aliases for testing variants that can be
combined with other variant names. E.g. --variants=dev,foo
would run the three developer default variants and variant
foo.
We'll have three stages: "dev" for variants to be run by
default on developer workstations, "more" for additional
variants, executed on all bots, "extra" for additional
variants executed on a subset of bots (e.g. not on very slow
or otherwise resource-limited bots).

be used when running ignition tests in isolation on the bots.
The bots only use ignition_turbo in isolation since a while
and don't pass the --ignition flag anymore.

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 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.

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.
