[v8][wasm] Increase the limit on sync compilation on the main thread

With the introduction of the baseline compiler Liftoff and lazy
compilation, the execution time of synchronous WebAssembly compilation
has decreased significantly. Additionally hardware has improved since
the definition of the original limit of 4KB. Therefore this CL
increases the limit to 8MB.

The limit was determined by performance measurements on a Google
Pixel 1, which we considered as a representative low-end phone. This
phone was able to compile an 8MB module in less than 200ms, which is
the threshold for good responsiveness in the metric "interaction to
next paint" defined by Google's Core Web Vitals.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
