My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.
There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.
Drive by: debugger-script.js and usage of debugger context in inspector code base.

just stick around and are also not being inlined because the heurstic

This removes the --turbo flag and solely relies on the filter pattern

that disabling optimization wholesale can still be done with --no-opt,
which should be used in favor of --no-turbo everywhere.
Also note that this contains semantic changes to the TurboFan activation
criteria. We respect the filter pattern more stringently and no longer

of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

That is, a JSLoadModule with a Module HeapConstant input becomes
a LoadField with a Cell HeapConstant input, and similarly for
JSStoreModule.
