7d468b70cd [TurboProp] Make TurboProp optimize later.
Moves TurboProp to optimize around the time of TurboFan right now, and
removes some of the special-case logic we had to avoid aggressive
early optimization of TurboProp.

1ac40e69e8 [system-analyzer] Support inline scripts
Inline scripts share the same URL, so lookup of script by URL on them
can give the wrong result. Also, their source positions are relative to
the start of the HTML file, so we need to infer the starting line from
the Script's compilation event.

As a drive-by, fix the tooltip to lock in-place on click.

79b6158757 [system-analyzer] Support thin ticks
Add better support for lots of thin ticks by:

  * Removing stroke on ticks (so that the stroke isn't thicker than the
    tick itself)
  * Alternating colours of the ticks between light and dark (so that
    neighbouring ticks are still distinguishable)
  * Making selection drawing use isInputPending to allow faster looping
    over multiple ticks.

f370d60711 [test] Add verbose output of flaky tests
The verbose output shown on bots didn't print the first failing result
of a flaky test before. Now the result line shows all results and
the details in the end show the output of the first failure.

Previously it was confusing as it seemed that the json results and
the test runner output differed.

We now print PASS in all caps like the other statuses. A test for
this case already existed and the output is now updated.

c21d0148d6 [testrunner] Implicitly detect trivial flag contraditions
This changes the test runner to automatically treat cases in which
both a flag and its negation are present as a flag contradiction.
Example: "--foo --no-foo".

With this change it's no longer necessary to explicitly specify these
trivial contraditions in variants.py.

Note: since negations are created through simple string operations,
bogus constructions are possible ("--nobodys-perfect" ->
"--bodys-perfect"). We accept these as unlikely-to-cause-problems.

ee56a9863e [test] Run heavy tests sequentially
This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.

The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.

The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

54d84cf385 [wasm-c-api] Cache CapiCallWrappers in the NativeModule
We used to recompile WasmCapiCallWrappers whenever they were
needed, but never garbage-collected them, which caused a memory
leak when many short-lived instances of the same module were
created. This patch makes the wrappers cacheable and caches them,
which avoids both repeated compilation effort and the unbounded
memory growth.
Drive-by cleanup: unify WasmCapiFunctionData with the other
Wasm*FunctionData classes by making it inherit from WasmFunctionData.
