e21f9ab42b [x86] Allow (v)divsd->(v)mulsd to execute in parallel.
This tweak was already present in CrankShaft for the non-AVX case. As it
turns out, it's also relevant even with AVX. Now the same optimization
is applied in case of TurboFan as well.

d646fcc2f0 PPC: [turbofan] Materialize JSFunction from frame if possible.
Port 725cdc533c

Original commit message:
This reduces the overhead of recursive calls when context specialization
is enabled. Based on this it might be possible to further reduce the
overhead by also specializing the call itself.

As a drive-by-fix, port the fast context materialization optimization to
arm and arm64, that was previously only supported on x64 and ia32.

Port 35a67b745d

Original commit message:
Thanks to some careful assumptions, we can examine the object found at
vector[slot] and trust it's a heap object where the second field is
either a map if it's a WeakCell, or definitely not a map if it's a
Symbol, String or FixedArray. Use this to save a memory read.

052924abe3 Speculative fix for stack overflow in CollectEvacuationCandidates
I don't have a repro, but it seems that when we are close to the stack limit,
CollectEvacuationCandidates' local variables can blow the limit. To avoid
this, instead of always allocating a 2000-pointer-sizes array on the stack,
use a std::vector (which stores its elements on the heap), and while we're
at it, only allocate as many elements as we actually need.

35f6c0fdbf [turbofan] Optimize silent hole checks on legacy const context slots.
Currently we always generate a diamond in the graph builder for every
legacy const context slot, which we cannot get rid of until late control
reduction, even if we know after context specialization that the slot is
already initialized.

Now we generate a select instead, which the CommonOperatorReducer
happily removes during typed lowering. This greatly speeds up asm.js
code generated by Emscripten with the new POINTER_MASKING mode.
