      [math] Fix Math.hypot to properly call ToNumber on all arguments. · 264fa75e
      bmeurer authored 
      The spec requires all Math functions to first call ToNumber on all
arguments before doing any other observable operation.  So early
return in case of Infinity is not valid.

Drive-by-fix: Remove the use of %_Arguments / %_ArgumentsLength and
use (strict) arguments instead of allocating a temporary InternalArray
explicitly.

      [i18n] Replace uses of %_Arguments/%_ArgumentsLength with arguments. · db74cccf
      bmeurer authored 
      No need to micro-optimize here, and in almost all cases here, using
arguments should result in roughly the same code w/ Crankshaft anyway.

      [turbofan] fine grained in-block move optimization · 1ecf58f4
      mtrofin authored 
      So far, we've been moving down gaps wholesale. This change moves
individual move operations instead. This improves some benchmarks,
and should overall reduce code size, because it improves the chance of
reducing the number of moves.

For example, there are improvements on x64 in Emscripten (Bullet, in
particular) , JetStream geomean, Embenchen (zlib).

In the process of making this change, I noticed we can separate the
tasks performed by the move optimizer, as follows:

- group gaps into 1
- push gaps down, jumping instructions (these 2 were together before)
- merge blocks (and then push gaps down)
- finalize

We can do without a finalization list. This avoids duplicating storage -
we already have the list of instructions; it also simplifies the logic, since,
with this change, we may process an instruction's gap twice.

Compile time doesn't regress much (see pathological cases), but we
may want to avoid the allocations of the few sets used in the new code.
I'll do that in a subsequent change.
