c445e1e96b [Compiler] Remove EnsureBaseline.
We only optimize functions which are already compiled, so there is no need
to ensure baseline in pipeline.cc, and since ast-graph-builder doesn't
do inlining, there are no other uses.

f251e9501c [fullcodegen] Remove support for bailout preparation.
This removes the ability to prepare bailout points in code generated by
the {FullCodeGenerator}. Such code is no longer used as the target of
deoptimization attempts, hence storing deoptimization data is obsolete.

9d23ec9f69 [turbofan] Remove deoptimization support from AstGraphBuilder.
The AST-based graph builder is by now only used for asm.js code. This
change hard-codes this assumption into the compilation pipeline and
hence allows us to remove support pertaining to deoptimization from
optimized code that was not derived from bytecode.

1fc93f2e2d [Compiler] Enable use of seperate zones for parsing and compiling.
In order to allow parallel compilation of eager inner functions, we need to
seperate the zone used for parsing (which will be shared between all the
parallel compile jobs) and the zone used for compilation. This CL changes
CompilationInfo to require a zone (which can be different from the zone in
ParseInfo). We then seal the ParseInfo zone after parsing and analysis is done
to prevent any further allocation in that zone, so that it can be shared
(read-only) with the parallel compile jobs.

There were once plans to generate cross-context code with TurboFan,
however that doesn't fit into the model anymore, and so all of this
is essentially dead untested code (and thus most likely already broken
in subtle ways). With this mode still in place it would also be a lot
harder to make inlining based on SharedFunctionInfo work.
