This CL removes some magic numbers used to convert floating values into integer values, and the corresponding comments describing how they were computed. It replaces these tests with template function is_inbounds() that makes the compiler automatically generate the appropriate constants and tests.

Remove the --extra-masking and --mask-array-index flags. Instead, use --untrusted-code-mitigations directly. This also changes the default for these flags: There were off by default so far, but --untrusted_code_mitigations is on by default.

Previously the Promise builtins would always use a runtime function to schedule a new microtask, which is unnecessarily expensive. Since the runtime function only adds the microtask to a FixedArray (potentially growing that array) and increments the number of pending microtasks, it is fairly straight-forward to do this in CSA land instead. This change improves the Bluebird benchmarks by 2-4% on average.

The Promise builtins call out to arbitrary JavaScript a lot, but always use the generic Call builtin with the "any" mode, which means that the builtin has to dispatch based on the type of receiver. Yet these builtins always know for sure that the receiver is either undefined or definitely not null or undefined. So this changes the builtins to pass the correct ConvertReceiverMode and thus save a couple of checks.

This adds support for get_local and set_local to the wasm compile fuzzer. Each function will have between 0 and 32 locals of random type. For set_local, we generate a value of the respective type and store it in the local. For get_local, we load any local and convert it to the wanted type. Note that with get_local, we now also check that parameters are passed correctly between functions. Drive-by: Fix parameters passed to the main function (was [1,2,3] for the interpreter, but [1,1,1] for compiled code).
