Frame slots indexes numbers are used more consistently for
computation in both TurboFan and Crankshaft. Specifically,
Crankshaft now uses frame slot indexes in LChunk, removing
the need for some special-case maths when building the
deoptimization translation table.

This removes the language mode parameter from all JSCall operators. The
information is no longer used anywhere and is not threaded through the
interpreter bytecode. We should only thread it through the bytecode if
it has a semantic impact on the compilation.

Everything that HCallStub does can easily be done using the more general
HCallWithDescriptor, so there's no need to have this dedicated

If sweeping is in progress then we need to filter out slots in free space after
array trimming, because the sweeper will add the free space into free list.

This CL also fixes a bug in SlotSet::RemoveRange.

There's no point in having the setup or the toString/valueOf methods in
JavaScript. The full setup can be done during bootstrapping when the
Boolean constructor is created, and the prototype methods don't benefit
from JS + %_ at all.

Port fd8fd05c

Original commit message:
This functionality is useful for stubs that need to walk the stack. The new
machine operator, LoadParentFramePointer doesn't force the currently compiling
method to have a frame in contrast to LoadFramePointer. Instead, it adapts
accordingly when frame elision is possible, making efficient stack walks
possible without incurring a performance penalty for small stubs that can
benefit from frame elision.

  Turn the fast case of ArgumentsAccessStub into a new stub
  FastNewSloppyArgumentsStub, which is similar to the existing
  FastNewStrictArgumentsStub, although not polished yet, and the slow

CPU profiler probes stack frame to find if it's in a valid

  original commit message:
  The FastNewStrictArgumentsStub is very similar to the recently added
  FastNewRestParameterStub, it's actually almost a copy of it, except that
  it doesn't have the fast case we have for the empty rest parameter. This
  patch improves strict arguments in TurboFan and fullcodegen by up to 10x
  compared to the previous version.

  Also introduce proper JSSloppyArgumentsObject and JSStrictArgumentsObject
  for the in-object properties instead of having them as constants in the
  Heap class.

  Drive-by-fix: Use this stub and the FastNewRestParameterStub in the
  interpreter to avoid the runtime call overhead for strict arguments
  and rest parameter creation.

This enables downloading all gcmole dependencies from
google storage on demand, controlled by a gyp flag
"gcmole=1". This makes the analysis portable to any linux64
host. The archive contains a prebuilt clang in the needed
version, the gcmole plugin and a lua binary.

The tool can be run through a new wrapper that sets up the
environment. This'll ease running it on swarming.
