This CL teaches the deoptimizer about JavaScriptBuiltinContinuation
frames that are not preceded by argument adapter frames. This pattern
is used when calling C++ API functions from TurboFan.
This CL fixes a crash when the deoptimizer encounters the pattern
described above. The crash was caused when the deoptimizer tried to
read the arguments of the continuation frame. As no adapter frame
was present, the argument count was read from the SharedFunctionInfo
which had the kDontAdaptArgumentsSentinel value. This translated to
an argument count of ~65000 later down the line, which caused a
FATAL error when the deoptimizer tried to re-construct ~65000
non-existent values.
