Since code objects cannot grow larger than 2GB anyway, it's enough to store the instruction offset and landing pad offset as 32-bit values. This reduces the size of the ProtectedInstructionData struct by 50%.

This CL teaches the respective bytecode handlers and standalone stubs about BigInts, and collects "kBigInt" feedback for them.

This fixes the signature of "Math.abs" from "(signed) -> signed" to "(signed) -> unsigned" and hence fixes cases where the absolute value would overflow the range of signed 32-bit values. This is in sync with spec erratas (and ECMAScript semantics). Note that this also switches the underlying implementation of the above absolute value function to a branch-free version.

In the test-run-wasm and test-run-wasm-64 cctests it is not possible to call runtime functions. To test traps in these cctests we therefore replace the runtime call with a call to a c-callback, followed by a return. This CL fixes the problem that the return did not clean up stack parameters. This CL unblocks https://chromium-review.googlesource.com/c/v8/v8/+/671008. Originally I wanted to mitigate the problem in that CL by defining an additional parameter register for arm. However, adding additional parameter registers lets other tests fail.
