[turbofan] Remove explicit context specialization from inlining.

[turbofan] Remove explicit context specialization from inlining.

Ideally inliner itself should not deal with context specialization at
all, since this is all handled in the pipeline instead (actually
inlining already runs together with context specialization), and the
inlining logic should not care about the specialization mode.

Hey Jaro,

This code is now obsolete, as inlining and context specialization run together
in the Pipeline. Please take a look.

Thanks,
Benedikt
