We used to emit debug break location on block entry. This cannot be
ported to the interpreted as we do not emit bytecode for block entry.
This made no sense to begin with though, but accidentally added
break locations for var declarations.
With this change, the debugger no longer breaks at var declarations
without initialization. This is in accordance with the fact that the
interpreter does not emit bytecode for uninitialized var declarations.
Also fix the bytecode to match full-codegen's behavior wrt return
positions:
- there is a break location before the return statement, with the source
position of the return statement.
- right before the actual return, there is another break location. The
source position points to the end of the function.

Adds support for cpu profiler logging to the interpreter. Modifies the
the API to be passed AbstractCode objects instead of Code objects, and
adds extra functions to AbstractCode which is required by log.cc and
cpu-profiler.cc.
The main change in sampler.cc is to determine if a stack frame is an
interpreter stack frame, and if so, use the bytecode address as the pc
for that frame. This allows sampling of bytecode functions. This
requires adding support to SafeStackIterator to determine if a frame is
interpreted, which we do by checking the PC against pre-stored addresses
for the start and end of interpreter entry builtins.
Also removes CodeDeleteEvents which are dead code and haven't
been reported for some time.
Still to do is tracking source positions which will be done in a
followup CL.

This patch moves iterator finalization (calling .return() when a
for-of loop exits early) to shipping. The only part of this feature
which is currently known to be missing is destructuring--.return()
should be also be called when destructuring with an array which
does not end in a rest pattern, but it currently does not. The rest
of this feature, including calling .return() from certain builtins,
is implemented.

It is possible for JS objects to be allocated while we are retrieving the

Adding these to the profile data structures invalidates the iterators that

The previous versions of Math.max and Math.min made it difficult to
optimize those (that's why we already have custom code in Crankshaft),
and due to lack of ideas what to do about the variable number of
arguments, we will probably need to stick in special code in TurboFan
as well; so inlining those builtins is off the table, hence there's no
real advantage in having them around as "not quite JS" with extra work
necessary in the optimizing compilers to still make those builtins
somewhat fast in cases where we cannot inline them (also there's a
tricky deopt loop in Crankshaft related to Math.min and Math.max, but
that will be dealt with later).
So to sum up: Instead of trying to make Math.max and Math.min semi-fast
in the optimizing compilers with weird work-arounds support %_Arguments
%_ArgumentsLength, we do provide the optimal code as native builtins
instead and call it a day (which gives a nice performance boost on some
benchmarks).

The CL https://codereview.chromium.org/1409013004 added / changed some test cases.
Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result
check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined
functions has different behavior comparing with GCC ia32 build and x87 build. The major
difference is sse float register still has single precision rounding semantic. While X87
register has no such rounding precsion semantic when directly use register value. The V8
turbofan JITTed has exactly same result in both X87 and IA32 port.
So we add the following sentence to do type case to keep the same precision.
float expect = *i * *j; // *i + *j, etc.
For test case "RunFloat64MulAndFloat64Add1 / RunFloat64MulAndFloat64Add2 / RunFloat64MulAndFloat64Sub1
/ RunFloat64MulAndFloat64Sub2", the expected result calcaulated by GCC has difference precsion
when comparing with V8 turbofan result for X87 platform. (Turbofan X87 result is the same as
IA32 GCC and IA32 Turbofan). So we have to disable those four cases for X87 port.

This change makes possible to save and restore the FP registers
in the Prologue and Return parts for the CallAddress kind functions.

This has become necessary as we have more experimental natives
that run after deserializing from the snapshot.

The failure was been triggered by turning on --harmony-arrays,
maybe because code size was increased or code was added later
in the bootstrap process. Because it doesn't look like a bug
in anything guarded by --harmony-arrays directly, I'd suggest
shipping the flag and disabling the test on the architectures
where it's been observed to fail. It's already disabled on arm64
and this patch disables it on mips64 as well.
