3ad973a16f Fix broken JSFunction::is_compiled predicate.
The aforementioned predicate reported a JSFunction that was marked for
optimization as already compiled. This in turn also prevented us from
being aggressive about FLAG_always_opt treatment.

1caa6179d2 X87: Switch full-codegen from StackHandlers to handler table.
port 38a719f965  (r27440)

original commit message:

    This switches full-codegen to no longer push and pop StackHandler
    markers onto the operand stack, but relies on a range-based handler
    table instead. We only use StackHandlers in JSEntryStubs to mark the
    transition from C to JS code.

    Note that this makes deoptimization and OSR from within any try-block
    work out of the box, makes the non-exception paths faster and should
    overall be neutral on the memory footprint (pros).

    On the other hand it makes the exception paths slower and actually
    throwing and exception more expensive (cons).

f13d04d28c Return timestamp of the last recorded interval to the caller of HeapProfiler::GetHeapStats
Before this patch the embedder could assign timestamp to the last interval after calling GetHeapStats. This would be slightly different from the timstamps assigned by v8 internally and written into heap snapshot. This patch allow to avoid this small discrepancy by returning timestamp along with last heap stats update.

5d5bf2b77f X87: VectorICs: keyed element loads were kicking out non-smi keys unnecessarily
port 6689cc27eb (r27377)

original commit message:

    Handlers should be in charge of this work. The change uncovered a bug in
    vector-ics related to keyed loads into strings. It's important for
    StringCharCodeAtGenerator, a helper used in full code and in
    LoadIndexedStringStub (a handler) to protect the vector and slot registers
    when it makes a runtime call to convert a HeapNumber to a Smi.

    It's still possible for the handler to MISS after this call, perhaps due
    to out of bounds access. In that case, the vector and slot registers need
    to be delivered safely to the MISS handler.
