Check the return value of API calls on ia32 and x64.
...
This implies that the return value of native getters is checked. The nice part
is that one can even see the name of the property in question in the abort
output when the check failed.
Under some circumstances even the return value of interceptors gets checked, but
I'm not 100% sure about this, because the interceptor code is basically tuned to
death.
The change seems to have very low overhead, so it might be feasible to keep this
check enabled unconditionally.

Allocate block-scoped global bindings to global context.
...
- The global object has a reference to the current global scope chain.
Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
var and function still live on the global object.
(Lexical bindings are not reflected on the global object at all,
but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
the chain into account.

The reason for disabling optimization of a given function is carried around in
CompilationInfo. The new mechanism is general enough that --trace-opt now
subsumes everything --trace-bailout could print, so we nuked the latter flag.

Make order of addition the primary order of descriptor arrays.
...
The order by name is maintained as secondary order by using unused bits in the property details.
This is preliminary work towards sharing descriptors arrays.
The change allows us
- to get rid of the LastAdded bits in the map, binding it to the number of valid descriptors for the given map
- to avoid resorting by enumeration index to create the cache
- (maybe in the future, depending on performance) to get rid of the enumeration cache altogether.
Although generally the number_of_descriptors equals the NumberOfOwnDescriptors in the current version, this is preliminary work towards sharing descriptors, where maps may have more descriptors than are valid for the map.

xmm0 is not saved across runtime call on x64 because MacroAssembler::EnterExitFrameEpilogue preserves only allocatable XMM registers unlike on ia32 where it preserves all registers.

Safe operations are those that either do not observe unsignedness or have special support for uint32 values:

- >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side;
- >>> shift: it performs ToUint32 on both inputs;
- stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise";
- HChange: special support added for conversions of uint32 values to double and tagged values;
- HSimulate: special support added for deoptimization with uint32 values in registers and stack slots;
- HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.

Deoptimization support for accessors.
...
Highlights of this CL:
* Introduced a new opcode in the deoptimizer for a setter stub frame.
* Added a global setter stub for returning after deoptimizing a setter.
* We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution. If this hurts us one day, we can parameterize and reuse the setter deopt machinery.

Inline simple setter calls.
...
Currently only simple setter calls are handled (i.e. no calls in count
operations or compound assignments), and deoptimization in the setter is not
handled at all. Because of the latter, we temporarily hide this feature behind
the --inline-accessors flag, just like inlining getters.
We now use an enum everywhere we depend on the handling of a return value,
passing around several boolean would be more confusing.
Made VisitReturnStatement and the final parts of TryInline more similar, so
matching them visually is a bit easier now.
Simplified the signature of AddLeaveInlined, the target of the HGoto can simply
be retrieved from the function state.

Use the correct oracle in TestContext::BuildBranch.
...
When inlining is being done, it is crucial to use the correct type feedback
oracle with a given type feedback ID. To ensure this, TestContext now carries an
oracle which is associated with the context's condition, and these are both used
together in TestContext::BuildBranch.
Note that in VisitReturnStatement and TryInline we are currently lucky that the
oracles don't go out of sync in an observable way, but this will change when we
inline setters. Therefore, there is no separate test case...

Force eager compilation of parenthesized functions.
...
This makes the compiler use eager compilation for function literals that
are parenthesized. We consider this to be a hint that the function will
be called immediatly and hence try to avoid parsing it twice. The parser
already respects this heuristic.

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.

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).

mksnapshot or a VM that is booted from a snapshot. --debug-code

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

breaks at points where application objects are encountered. So it will
not trip on cross-context leaks introduced by the application itself.

Move some Pop/Drop calls directly to the places where they are needed.
...
This is a refactoring-only CL and the fourth one in a series for enabling
inlining of accessors. Later when we try to inline accessor calls, their
arguments must still be on the expression stack, so we must not remove them too
early.

Move BuildCallGetter/BuildCallSetter up in the call chain.
...
This is a refactoring-only CL and the third one in a series for enabling
inlining of accessors. The goal of this CL is to move the builders for accessors
to the places where we might be able to inline them later, i.e. the VisitFoo and
HandleBar member functions of HGraphBuilder.
Extracted duplicate code into LookupAccessorPair.

Cleaned up Hydrogen function signatures related to property access.

This is a refactoring-only CL and the first one in a series for enabling
inlining of accessors. The naming and argument order has been unified a bit, and
some tests have been pushed to the caller in order to get a simpler
signature. Note that the latter temporarily introduces some code redundancy, but
this will be cleaned up in one of the next CLs.
