Subject: [PATCH] deps: V8: fix debug build

This is a (very) partial cherry-pick of upstream change v8/v8@f8fddd6b13
that fixes the following debug mode build error with clang:

    ../deps/v8/src/codegen/register.h:29:48: error: member reference
    base type 'RegListBase' is not a structure or union
      int num_different_regs = RegListBase{regs...}.Count();

Fixes: https://github.com/nodejs/node/issues/44371
PR-URL: https://github.com/nodejs/node/pull/44392
