This allows us to use them in constexpr contexts, just as DCHECK. There were some "constexpr" keywords missing, and we cannot have explicit template instantiations for constexpr.

Optimizes BitVector::Iterator::Advance by using base::bits::CountTrailingZeros to skip through bitvector. Also inlines Advance in the header.

This allows the tests to continue running on the gc fuzzers while staying compatible with the --force-slow-path flag being passed randomly. When run in slow_path variants these tests are no-ops, but that's negligible as the tests are also fast without slow_path.

UMA data shows that we currently still allocate up to ten code spaces per module. This is because the code size estimates are vastly off, especially if both Liftoff and TurboFan is being used. Also, code sizes differ by platform. This CL adds more logic to the {EstimateNativeModuleCodeSize} function to distinguish Liftoff and TurboFan, and to use different constants per platform. A largeish comment explains how the numbers were generated, and that they are an extreme over-generalization. However, without further information about the module, this is the best we can do. After all, being off even by a factor of two does not hurt too much, as explained in the comment.

On platforms that do not require the far jump table for wasm calls (32 bit platforms currently), we do not need to include a far jump table slot per wasm function. Other places already used the {NumWasmFunctionsInFarJumpTable} helper function, but in the actual allocation of the far jump table, it was missing.

We used the same random seed for all test cases of a fuzz session for transitioning from choosing the flags on V8 side. Since the grace period for stable bisection is over, we now use the same random number generator throughout the fuzz session which leads to a wider range of differently chosen flags.

This patch excludes brand symbols from the result of JSReceiver::GetPrivateEntries so that the brands do not show up when the instances are inspected from the DevTools (e.g. via `Runtime.getProperties()`). To implement this, we use a bit in the Symbols to denote whether it's a brand symbol. A brand symbol is also a private name symbol so that we can just reuse the IC for accessing private names and do not need to jump through extra ORs.

This creates a .tq file in src/objects for each src/objects/*.h file with Torque-defined classes and moves the object definitions and corresponding helpers/macros there. In addition, we create files convert.tq and cast.tq in src/builtins to move the casts and conversions to. Since Torque-generated .cc files end up as .o files in the same directory, there cannot be two .tq files of the same name. Thus it was necessary to rename src/builtins/arguments.tq and src/builtins/string.tq to not clash with the new files in src/objects. This is a mechanical change that only moves code.
