A GC in the access check callbacks NamedSecurityCallback and IndexedSecurityCallback
violates the contract about these callbacks.
Added a EXTERNAL VMState scope around the call to FailedAccessCheckCallback to be
consistent with the other callback invocations.

The first attempt did not properly handle keyed loads/stores and
did not check the constructors of the objects in the prototype
chain.
Added two more tests to handle the fixed cases.

Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.
This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.
As a side effect, we have also fixed the DebuggerAgent test.
Thanks to Vitaly for help in fixing isolates handling!

This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.
All other mips arch files are replaced with stubbed-out versions that
will build.
Arch independent files are updated as needed to support building and
running mips.
The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

Because we run all tests three times with different variant flags (to
test crankshaft) we might end up in a situation where we try to write
to the same serilization file from two different threads
simultaneously. The patch concats the variant flags at the end of the
serialization file name.

Record a safepoint with a deoptimization id for throw in optimized code. We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw). For
hygiene we use the actual ID of the throw expression. Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit. This is required to insert a simulate between the throw and the exit.
Make our optimized treatment of Function.prototype.apply act like a call and
have side effects. This ensures that it will get a lazy deoptimization
environment. Use that deoptimization ID in the safepoint for the call.
Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction. Record the
environment and use the deoptimization ID at the safepoint.

With crankshaft, a code object can change its optimizability: it can start as
optimizable code object, but later we can find out it was a bad idea to
optimize it. Alas, currently we don't have a proper event to communicate
this back to logger. Hence we temporary allow a code object to be viewed
as optimizable judging from logs while being unoptimizable judging from
heap traversal.

Fix a bug in the --debug-code alignment check in the C entry stub.
Don't force the --debug-code flag in the ARM disassembler tests. The framework does support passing flags and the test runner will when running tests in debug mode.
Skip some deserialization tests which crashes from time to time.

This change includes support for safepointtables and adding deoptimization info (but not for deoptimizing).
Implemented crankshaft functions:
CallCode
GenerateSafepointTable
RegisterEnvironmentForDeoptimization
EmitGoto
This change allows us to compile very simple functions with crankshaft:
An empty function
A function returning a constant.
A function returning a parameter.
There is 6 disabled tests that require us to be able to deoptimize
which is currently not supported.
