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.

The tests in question have been disabled because throwing into lazy
deoptimized code was borked. After recent fixes landed these tests
should now pass again.

This moves all cctest files for the compiler to live in the same
namespace as the components they are testing. Hence we can avoid the
forbidden using directives pulling in entire namespaces.
From the Google C++ style guide: "You may not use a using-directive to
make all names from a namespace available". This would be covered by
presubmit linter checks if build/namespaces were not blacklisted.

This removes the aforementioned flag which has been on by default for a
while now. Note that this does not control optimization decisions, only
the last-resort bailout in the graph builder.

TurboFan is now a requirement and supported by all backends, so we don't
need those macros (plus all the machinery on top) anymore.

This ensures there is a lazy bailout point at the entry of every
exception handler so that deoptimized code is not re-entered through
caught exceptions.

When compiling on a laptop I like to concatenate the small test files.
This makes a big difference to compile times. These changes make that
easier.

Replace the --turbo-deoptimization flag with --turbo-asm-deoptimization
and enable deoptimization for non-asm.js TurboFan code unconditionally.
