Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

It broke the Mac build.

Sampler::SampleStack() can't use Isolate::Current() when called from
the sampler thread (from SampleContext). We have to pass the isolate
pointer.

o Make ia32 macro assembler work without an isolate and use it in the
  custom memcpy creation code.
o Remove isolate-dependent code from the custom memcpy and modulo
  functions creation code.

In the cases where a global property cell cannot be used in the optimized code
use standard load ic to get the property instead of bailing out.

This is re-committing r7212 and r7215 which where reverted in r7239 with the addition of recoring the source position in the hydrogen code for the LoadGlobalCell instruction. To record that position an optional position field has been added to the variable proxy AST node.

Unoptimized code should already keep a reference to the SharedFunctionInfo,
let's use it instead of allocating a new object and prohibiting SharedFunctionInfo
