When BranchElimination has to find the common prefix of a set of BranchConditions in a Merge, it has to traverse a number of linked lists of individual conditions, which is inefficient. This CL improves its performance by grouping conditions between an IfTrue/IfFalse and a Merge in a single entry of BranchConditions. Additional change: Improve documentation of FunctionalList.

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.

This CL adds support for testing web snapshots through mjsunit tests. To allow for taking and using web snapshots from JavaScript, two methods, Realm.takeWebSnapshot() and Realm.useWebSnapshot(), are introduced in d8. Both of these methods accept a Realm as a parameter, allowing for mjsunit tests to create and use the snapshot in different realms. To return the snapshot data, Realm.takeWebSnapshot() creates and returns a snapshot object with the snapshot data stored as an embedder field.

BranchElimination and CsaLoadElimination interracted badly and created quadratic behavior when run together. This happened when CsaLoadElimination kept updating arguments of a Merge, and BranchElimination kept going through all of them to find the common prefix of all path conditions. Therefore, we separate BranchElimination and CsaLoadElimination in the csa and wasm optimization pipelines. Additional changes: - Split WasmOptimizationPhase from CsaOptimizationPhase. - Remove now-redundant argument from CsaOptimizationPhase::Run. - Fine-grain how statistics are measured in the wasm pipeline.

For memory accesses that are statically known to be in bounds, avoid the out-of-line code for the trap handler. This makes trap handler metadata smaller, reduces code size (by avoiding OOL code), and enables more optimizations at later phases, because unprotected memory loads can be reordered and reused. Drive-by: Use {GetMemoryAccessKind} consistently.

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.
