The addresses involved should always be aligned, so we can simply use
a cast, just like the ARM simulator. Even if the alignment assumption
did not hold and the platform we are running on couldn't handle
unaligned access, some #ifdefs would be much more preferable. The
affected member functions were the top 2 in a profile (18% and 15%),
so basically every hack is allowed here to speed things up. :-)

Removed some dead code for literals on the way. If we need to
resurrect it, we should do it without double(!) memcpys.

Generally, I still don't understand why we need the Instr/Instruction
distinction or simply wrap Instr within Instruction, this seems to
be much simpler and cleaner, but this would involve heavier changes.

The overall speedup of this CL is roughly 37%, see the numbers below

  - Return the correct NaN when an invalid operation generates a NaN.
  - When one or more operands are NaN, handle them as the processor
    would, prioritising signalling NaNs and making them quiet.
  - Fix fmadd and related instructions:
     - Fnmadd is fma(-n, m, -a), not -fma(n, m, a).
     - Some common libc implementations incorrectly implement fma for
       zero results, so work around these cases.
  - Replace some unreliable tests.

This patch also adds support for Default-NaN mode, since once all the
other work was done, it only required a couple of lines of code.
Default-NaN mode was used for an optimisation in ARM, and it should now
be possible to apply the same optimisation to A64.

- Distinguish between context bound scripts (Script) and context unbound scripts
(UnboundScript).
- Add ScriptCompiler (which will later contain functions for async compilation).

This is a breaking change, in particular, Script::New no longer exists (it is
replaced by ScriptCompiler::CompileUnbound). Script::Compile remains as a
backwards-compatible shorthand for ScriptCompiler::Compile.

Passing CompilerOptions with produce_data_to_cache = true doesn't do anything
yet; the only way to generate the data to cache is the old preparsing API. (To
be fixed in the next version.)

This is a fixed version of https://codereview.chromium.org/186723005/

Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.

Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.

The CL also brings back the type vector on the SharedFunctionInfo.

StopCpuProfiling is replaced with StopProfiling which returns non-const CpuProfile which allows to call CpuProfile::Delete on it without const_cast. Also replaced StartCpuProfiling with StartProfiling to have symmetric names for start/stop actions.
