      [ic] Completely unroll polymorphic IC map checks · 3c246db7
      jgruber authored 
      Polymorphic IC feedback can contain up to four (map, handler) pairs.

HandlePolymorphicCase already unrolled checks for the first two pairs; these
are guaranteed to exist and can omit bound checks.

This CL unrolls checks against the final two pairs as well.

      [ic] Inline LoadIC into LdaNamedProperty bytecode handler · 0bfabaf1
      jgruber authored 
      This inlines common LoadIC cases into the LdaNamedProperty bytecode
handler. Smi handlers resulting in constant/field loads for
monomorphic ICs omit frame construction. The same counts for the
polymorphic case as long as the target handler is in the first two
vector slots.

Other cases (megamorphic, uninitialized) call the new
LoadIC_Noninlined stub.

Local benchmarks show up to 6% improvement on Sunspider with --future.

      [ic] Fix StoreIC_SlowSloppy/Strict builtins. · 8f2245bf
      ishell authored 
      ... by using KeyedStoreIC_Slow builtin instead. The issue with hard-coded
language mode is that the stub can be re-used through megamorphic stub cache for
an IC with incompatible language mode. KeyedStoreIC_Slow already does the
right thing - it decodes the language mode from the IC slot kind.

This CL also fixes the code kinds of the slow IC handlers. The code kind of
IC handlers is used only for checking that the handler was added to the right
megamorphic stub cache, which expect the handlers' code kinds to be either
Code::LOAD_IC or Code::STORE_IC.

And the megamorphic builtins are just helper code stubs that are called from
IC dispatchers, therefore they should have BUILTIN code kind. Same applies to
the other stubs which are neither IC dispatchers nor handlers.
