Some pointers: By searching for "ExtraWide" in code search you can see e.g., this test code snippet:
https://source.chromium.org/chromium/chromium/src/+/main:v8/test/unittests/interpreter/bytecode-decoder-unittest.cc;l=32?q=extrawide&ss=chromium%2Fchromium%2Fsrc which tells us how the ExtraWide is used. The handler for ExtraWide is: https://source.chromium.org/chromium/chromium/src/+/main:v8/src/interpreter/interpreter-generator.cc;l=3308 I hope this helps.
