      [turbofan] Initial support for polymorphic inlining. · 7d4ab7d4
      bmeurer authored 
      For call sites where the target is not a known constant, but potentially
a list of known constants (i.e. a Phi with all HeapConstant inputs), we
still record the call site as a potential candidate for inlining.
In case the heuristic picks that candidate for inlining, we
expand the call site to a dispatched call site and invoke the
actual inlining logic for all the nested call sites.

Like Crankshaft, we currently allow up to 4 targets for polymorphic inlining,
although we might want to refine that later.

This approach is different from what Crankshaft does in
that we don't duplicate the evaluation of the parameters per polymorphic
case. Instead we first perform the load of the target (which usually
dispatches based on the receiver map), then we evaluate all the
parameters, and then we dispatch again based on the known targets. This
might generate better or worse code compared to what Crankshaft does,
and for the cases where we generate worse code (i.e. because we have
only trivial parameters or no parameters at all), we might want to
investigate optimizing away the double dispatch in the
future.

      [test] Fix the noi18n trybot · bcc3cb2e
      machenbach authored 
      This is a work-around as v8_enable_i18n_support=false does
currently not imply icu_use_data_file_flag=false. The
swarming isolator then tries to find the data file also
in builds without ICU.

Making the implication is non-trivial as icu_use_data_file_flag lives
in ICU and v8_enable_i18n_support lives in V8.
