77a7d9f539 Fix caching of optimized code for OSR. 
This makes sure we do not share optimized code across closures that were
optimized using OSR (for a particular OSR entry AST id) even if caching
of optimized code kicks in.

f37f504de5 Fix arguments object materialization during deopt. 
This fixes materialization of arguments objects for strict mode functions during
deoptimization. We materialize arguments from the stack area where optimized
code pushes the arguments when entering the inlined environment. For adapted
invocations we use the arguments adaptor frame for materialization.

f6cd2403e3 Fix deoptimizer for shared optimized code. 
The deoptimizer searched the stack for activations of the same function to
determine whether to trigger lazy deopting. Since we share optimized code we
actually need to search for activations of the same code (but potentially
different functions).

7af6883098 Fixed deoptimization of inlined getters. 
It is necessary to explicitly handle the internal frame lying between the caller
of the getter and the getter itself in the deoptimizer: When the getter is
inlined, leaving the internal frame restores the correct context.

83fc4205f6 Fixed compound/count operations with getter-only accessor properties. 
The underlying problem is that for compound/count operations we use the *load*
type feedback for storing, too. For normal properties this doesn't matter, but
for accessor properties we should better use the *store* type feedback, which
would be available, too. This consistent feedback usage could be guaranteed if
we removed the heavy copy-n-paste in the crankshaft code generation for
compound/count operations and assignments/property loads.

To be on the safe side, we postpone this refactoring and do a quick and easily
mergeable fix.

b8a7abd1fc Perform HasFastProperties check on prototypes when computing call targets in Crankshaft, part 2. 
The previous fix was for "real" calls, this one is for getters. It is a bit
unfortunate that this has to be fixed twice: We should really break up
Call::ComputeTarget into a predicate and 1 or 2 getters, so code can be reused.

The regression test has been modified a bit to make things more uniform.
