- Remove obsolete BreakLocatorType.
- Perform PrepareStepOnThrow after OnException event, in case stepping
was scheduled in the exception event.
- Use frame count instead of frame pointer for stepping. Frame pointer
is not reliable due to possible deopts.
- Consistently check for inlined functions in inlined frames.
- Use SharedFunctionInfo in FloodWithOneshot and EnsureDebugInfo.

The mentioned asserts did not work properly with interpreted and turbofanned functions.
To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value.
This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(),
isOptimized(fun), etc.

Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.
We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.

dispatcher. This enables these tasks to be performed in parallel to
compilation of the outer functio (only for Ignition functions).
We currently synchronize to ensure all inner function compilations
are complete before executing the outer function - future work will
allow outer function execution to happenin parallel to inner function

The inspector cannot deal with breaking inside of debug-evaluate.
There is therefore no point in supporting that in the debugger.

Wasm frames are special in that they have a non-integer script id
in inspector. The way we treat script ids currently is a bit of a mess -
our runtime functions expected integer IDs while inspector has string
IDs (which contain integers, except for Wasm frames). This will need to
be cleaned up once more Wasm tests are added.
The meaning of line/column numbers has also changed; the old JS debug
API encoded the function index and byte offset into line/column numbers,
while inspector-based API actually translates into lines/columns in the
disassembly.
