Even though a previous patch made the number of slots pushed/claimed on the stack aligned, the boundary between frames was not a multiple of two slots as well. We were pushing the number of arguments (which belongs in the ArgumentAdaptor frame) together with the arguments to pass to the callee (which belong to the frame of the callee). Those need to be separated so we can drop the arguments without messing up the alignment.

This fixes String::MakeExternal() to bail out if the subject string doesn't fit a regular ExternalString, instead of creating a short external string. The observation here is that for short external strings the overhead of having to have the StringResource plus going to the runtime/C++ for each and every character access from JavaScript land is probably bigger than the anticipated benefits. If this turns out to be wrong and there's a real benefit, we should make use of ThinStrings instead of having a separate way to represent external strings.

In order to test that we don't repeatedly go through the WasmCompileLazy runtime function, add a flag to the LazyCompilationOrchestrator to "freeze" it, i.e. disallow any further lazy compilation. In tests, use this flag to first call a method, then freeze lazy compilation, then call the method again to assert that no further lazy compilation is triggered. This test currently fails with --wasm-jit-to-native, so disable it for that variant.

Benedikt Meurer authored
Strings are immutable in JavaScript land (contrast with the runtime, where we can truncate strings that haven't escaped to JavaScript yet), so the length of a String is immutable. Thus loading the length of a String is a pure operation and should be expressed as such (i.e. doesn't depend on control or effect). The StringLength operator does exactly this and is hooked up to the effect chain in the EffectControlLinearizer. This will eventually allow us to simplify the optimization of string concatention and other operations that are a bit cumbersome in TurboFan currently, and it will also allow us to optimize string operations across effectful operations, for example combining multiple invocations to String#slice with the same inputs.

This is in preparation of adding a dedicated StringLength operator that loads the string length. This way operations on strings don't sit in the effect chain anymore until the EffectControlLinearizer, which wires them. The NewConsString semantics could still be better, i.e. it could try to figure out the proper map instead of going for the CONS_STRING_TYPE always. But this change is meant to be just about pushing the logic down to the EffectControlLinearizer, which we didn't have initially when the ConsString handling was done. This also allows us to remove the handling of CONS_STRING_TYPE from the Deoptimizer, since the escape analysis no longer sees cons strings.
