5deec59302 Unify handling of bailout IDs for property loads. 
Renamed Property::ReturnId to Property::LoadId, which describes its use more
accurately. Compound assignments and CountOperations now consistently use
Property::LoadId() instead of their own CompoundLoadId/CountId.

b5da7279b1 Introduced TypeFeedbackId and BailoutId types. 
This is a refactoring-only CL which improves the typing of IDs associated with
AST nodes. The interesting parts are in utils.h and ast.h, the rest of the CL
basically follows mechanically.

b49b32599b Make AdjustAmountOfExternalAllocatedMemory() more robust. 
Do not crash if called from a thread without V8 isolate, reset the external
memory counters in case of overflow, bump the external allocation limit.

This will allow us to track typed array allocation and deallocation in WebKit.

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.

930aaf4267 android: refine custom ucontext_t definitions. 
This is a forward-compatible change to avoid type/naming
conflicts when the Android platform/NDK will update its
<signal.h> header to properly define 'struct sigcontext',
'mcontext_t' and 'ucontext_t'.

In particular:

  - Do not define 'struct sigcontext.h' to avoid
    conflicts with the C library definition (which
    is different, see below).

  - Only provide custom ucontext_t declarations if
    the Android <signal.h> doesn't provide it. This can
    be tested with a macro check (__BIONIC_HAVE_UCONTEXT_T)

+ Use 'gettid()' on Android since it is available (at all
  API levels).

1d0f872ef9 Fix full code generator to not use --debug-code if it is in 
mksnapshot or a VM that is booted from a snapshot.  --debug-code
can still have an effect on stub and optimized code and it still
works on the full code generator when running without snapshots.

The deoptimizer generates full-code-generator code and relies on it having
the same layout as last time.  This means that the code the full code
generator makes for the snapshot should be the same as the code it makes
later.  This change makes the full code generator create more consistent
code between mksnapshot time and run time.

This is a bug fix and a step towards making the snapshot code more robust.

76fe67b092 Implement verification of context separation. 
This adds the --verify-global-context-separation flag which can be used
to verify that no code object embeds pointers to more than one global
context after a full GC. It uses an object visitor that just performs
shallow traversal of the object graph spanned by one code object, and
breaks at points where application objects are encountered. So it will
not trip on cross-context leaks introduced by the application itself.
