Deserialization is currently split into three main steps:
1) Read code and allocate code buffer
2) Copy and relocate code
3) Publish
This moves step 2) to a background task so that it can concurrently
process work units added to the work queue by step 1).
Next, step 3) will also be moved to a background task to create a full
pipeline, such that we can start publishing the first units almost
immediately.

all_true, any_true, bitmask, and extract_lane all replace a simd type
with single scalar, so we don't need to set nullptr for the extraneous
lane, and can set num_lanes to 1.
So for a call node with any of the above nodes as one of its value, we
were incorrectly replacing the extract lane node with 4 nodes - it
should only be 1 scalar node.
Drive by fix for LowerShift, it needs to check if the shift value node
has replacement (e.g. if it is an extract lane node).
Also we weren't setting the lowered type of a kPhi node. This can be a
problem if the output of a Phi node is used by a F32x4ExtractLane and
I32x4ExtractLane, which is possible (and type correct since both take
v128). This will require that the output be both a float and a int,
which is impossible. So fix it to Int32x4, and the uses of the phi nodes
will convert appropriately.
Added a test for the call node. Also tested this code by running one of
our benchmarks, which exercises the Phi logic.

S128Select and S128AndNot relies on the inputs being lowered to I32x4,
since they use Word32Xor, but it wasn't correctly specified. This means
that by default, their lowered type was set to be the output's lowered

then their lowered type will be set to Float32x4, so the inputs will be
lowered to Float32x4, and we get incorrect type of registers allocated.

This CL reverses the count logic for the tiering strategy of the
js-to-wasm wrappers. The initial approach was that calls to each
function were counted up, until a threshold was reached and the function
would tier up. With this CL, each function is assigned a budget of calls
that can be handled through the generic wrapper. Calls are counted down
until the budget is exhausted, which will trigger the tier-up
for the function.
This approach comes with two advantages. Firstly, determining whether
a function's budget is exhausted is as simple as checking the flags set
from the decrement of the budget. Secondly, the code generated by the
generic wrapper does not depend on the specific value of the initial
budget.

As part of an effort to prepare the Recorder interface for general use,
we had to make some changes to the way the existing Wasm Events are
being used. In particular,
- it is more fitting to use a ElapsedTimer than a TimedScope to
measure the durations in src/wasm/module-[decoder|instantiate].cc
- we want to rename the wall_clock_time_in_us field to duration_in_us
for clarity.
Because these Wasm events are already being instantiated in chromium,
renaming the field requires a two-step change. This is the first of
those changes.

Prototype these two instructions on ia32. They are movss and movsd
respectively, so the implementation is pretty simple, as we support
these instructions already.

https://crrev.com/c/2468618
This CL adds the same set to the wasm interpreter.
We also need to make sure "negation" as well as
"std::abs" are excluded from this fix as they can reverse
the sign bit intentionally.
