Initializing the compilation progress first, and making it an explicit
step, allows us to share the wrapper compilation code between async
compilation and streaming compilation. In the future it will also allow
us to initialize compilation units based on the compilation progress,
which will allow us to share more code between async compilation and
deserialization.

We were just printing "Liftoff" in the compiler field, whichout a way to
tell if it's Liftoff's debugging code flavour or default Liftoff code.
This CL encodes that in the "compiler" field by selecting between
"TurboFan", "Liftoff", and "Liftoff (debug)".

These changes are found after Cobalt rebased to V8 v8.8. Most changes
are grouped into their own CLs and here are the rest.
- Replace raw printf with PrintF
- Include Starboard as a platform for some implementations
- Add some missing headers. This is probably because Cobalt does
  not compile all of V8 sources so some missing headers are only exposed
  when compiling Cobalt.

These indicate when a range-based for loop is using an index whose type
(value, pointer, or reference) doesn't match what the loop actually
extracts from the range.  Fix by matching the actual type better.

This shouldn't cause any behavior/performance change, just be slightly
clearer about what's actually happening when reading the code.

This CL modifies the underlying storage of PerIsolateAssertScope from
a bitfield to separate booleans. This slightly increases the space taken
by the isolate, but allows for easier access to the individual fields,
which is a prerequisite for implementing assertion scopes in TurboFan.

It also refactors the template PerIsolateAssertScope class to separate
simple C++ scope classes, defined through macros.

We've seen Turbofan take excessive amounts of time for very large
functions. As a short-term mitigation, this patch disables optimization
for functions larger than 500KB (in their Wasm binary format).
Functions of such sizes are rare, so most modules should be unaffected
by this patch.
