This CL introduces the necessary infrastructure to generate speculative BigInt operations in case of BigInt feedback. In particular, the JSAdd operator is lowered to a speculative call to the BigIntAdd builtin, with a deopt bailout in case of exceptions or violated assumptions.

Currently, probabilities for extra flags are calculated in the correctness fuzzer harness, which makes the RNG fragile when bisecting backwards, when the script's config changes during bisection. This adds the possibility to pass extra flags on command line to the script. After a grace period, we will migrate the flag calculation to clusterfuzz.

Perform a best-effort check for module context and provide an appropriate error. As seen from the import-blah-script.js test, we could have invalid import expressions in a script context that could result in an error saying "Cannot use import statement outside a module" which isn't the ideal error because the error is an incorrect import expression. But, when the developer changes to a module context, the correct error is thrown. To fix this, we'd have to refactor and call ParseImportDeclaration, and then throw an appropriate error, which seems like a lot of overhead for not enough gain.

This CL refactors the type-checking for br_table instructions. Originally, we iterated over all targets of br_table and checked if the values on the stack match the types expected by the target's signature. However, this caused problems with type checking unreachable br_table instructions where some stack values are unavailable. According to the anyref proposal, the expected type of br_table is the greatest lower bound of all its targets. With the existing implementation, the expected types were the types of the first target. With this CL, we first calculate the expected types of br_table, and only then inspect the stack if matching values are available.

To correctly fuzz the behaviour of optimized code and ICs we need to allocate feedback vectors. So for the configurations testing these we should turn off lazy feedback allocation. It is also good to fuzz without lazy feedback allocation on other configurations to flush out any other issues. So we also fuzz this with 0.35 chance. We also fuzz aggressive lazy feedback allocation (allocate feedback vectors on first branch / return) with 0.05 chance to test corner cases related to lazy feedback allocation.

This is a CL that aims to do a general cleanup of DecompressionElimination to make it easier for devs to look at it, and to create new test cases. Combined direct decompression & compression tests since they can be summarized with a for loop in just one test that tries out all the combinations. Also created 'global' accesses to stop repeating them in every test. Same for compression and decompression ops. Added EXPECT in test cases that had none. Added dots after comments. Variables now use underscore instead of camelCase.

This CL deduplicates entries in constant pools based on handle location. This works well because we already use CanonicalHandleScope in the right places. The CL gives a ~2% speed-up on octane for arm64. The code size is reduced significantly as well: Before the change all generated code spend on constant pools during an Octane run on arm64 was 723kb (90398 64bit words) before this change, and after this change only spend 189kb (23615 64bit words) were spend on constant pools. This is a 73.8% reduction.
