- Handle sparkplug code
- Handle regexp code-creation events in the tick-processor, which
have no valid state marker in the maybe_func data
- Remove calls to print() that break the tick-processor web version

This cl extends profview to
1. Show Turboprop ticks in a different color in timeline panel
2. In summary panel, show Turboprop optimizations and TurboFan
optimizations as two different entries
3. Fix deopts in summary panel after the rename to deopts
4. Also show information about bailouts (happen only with Turboprop)

If profiling is done with --log-source-code profview will now display
a "View source" link for each function in the tree view. Clicking this
will show a new source viewer, with sampled lines highlighted. See the
associated bug for screenshots.
This patch also fixes a bug in the profiler where the source info of
only the first code object for each function would be logged, and
includes some refactoring.

Rather than lumping in parsing, bytecode compilation and optimized
compilation all into the same VM "compile" state, seperate them out
into individual states. Additionally, add support for these states
to tickprocessor and profview.

This adds optimization and deoptimization counts to the Web UI. Also, the function timeline
now shows optimization and deoptimization marks.

When displaying a single function's timeline, display all its variants
(colour-coded by kind) instead of just the ones with the same code-id.
This allows us to see all optimised versions of a function, as well as
changes between optimised and unoptimised.
Drive-by -- Do some rounding to get rendering pixel-perfect.

Adds a bar below the current timeline view which can show the time
when an individual function was on the stack. Functions in the call
stack are now clickable to show them in this view.
Sections where the function was on the stack, but not at the top, are
displayed at half height.

The function list is now filtered by category by default, and sorting improved to break ties better.
Since the butterfly trees get massive, I had to start expanding the call trees on demand. This is implemented by keeping track of all ticks that cross given tree node (+ position where they crosses it). This seems to work quite well - in subsequent CL, I am planning to flip the bottom-up and top-down trees to use this.
