3f47c63ded [liveedit] reimplement frame restarting. 
Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.

We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.

26ecb4a1d7 [Turbofan] Add ia32 support for 4 and 16 byte moves and swaps. 
- Adds move/swap handling for 4 and 16 bytes to ia32.
- Register allocator now only requests 4 bytes for floats on ia32 and arm.
- We probably need similar support in mips.

d9e8764f81 [ic] Split LoadIC into LoadGlobalIC and LoadIC. 
The former will handle loads of predeclared global variables (vars and
functions), lets, consts and undeclared variables. The latter will handle
named loads from explicit receiver. In addition, named loads does not
depend of the TypeofMode.

TypeofMode related cleanup will be done in the follow-up CL.

479de28c3a Revert of Adding ia32 simd assembler changes. (patchset #2 id:20001 of https://codereview.chromium.org/1991713002/ ) 
Reason for revert:
Crashes on win32 debug:
https://build.chromium.org/p/client.v8/builders/V8%20Win32%20-%20debug/builds/2305/steps/Check/logs/stdio

Also, would be nice if the test output could be a bit shorter and only print what's necessary to trace a failure. Or split things into more smaller tests. Like that, these logs must be processed, json-encoded/decoded and sent around through the infrastructure.

Some chars in the output make the json encoder unhappy, therefore the infrastructure can't nicely display the failures.

1b23079936 [wasm] Int64Lowering of Int64Add on ia32 and arm. 
Int64Add is lowered to a new turbofan operator, Int32AddPair. The new
operator takes 4 inputs an generates 2 outputs. The inputs are the low
word of the left input, high word of the left input, the low word of the
right input, and high word of the right input. The ouputs are the low
and high word of the result of the addition.

ddc626e1cf [wasm] Int64Lowering of I64Shl on ia32. 
I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new
operator takes 3 inputs, the low-word input, the high-word input, and
the shift, and produces 2 output, the low-word output and the high-word
output.

At the moment I implemented the lowering only for ia32, but I think the
CL is already big enough. I will add the other platforms in separate
CLs.

8dad78cdbd [turbofan] Add backend support for float32 operations. 
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will
be added based on this later. Therefore this does not affect production
code except for some cleanup/refactoring.

In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
  backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.

In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and

e3e7daf01c We need to know if a load, store or call IC is assumed 
to be on the global object. Previously, this information
was stored in RelocInfo. A more logical place for this kind
of structural information is ExtraICState. Storing it there
makes it easier for us to gather type feedback from these
sites too.

5768fcf12c Fix the CPU feature detection. 
Move all of the CPU detection logic to the CPU class, and make
all other code use the CPU class for feature detection.

This also fixes the ARM CPU feature detection logic, which was
based on fragile string search in /proc/cpuinfo. Now we use
ELF hwcaps if available, falling back to sane(!!) parsing of
/proc/cpuinfo for CPU features.

The ia32 and x64 code was also cleaned up to make it usable
outside the assembler.

This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by

TLS access through explicit Isolate::Current() calls.

I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

e4edbb0535 Cleaned up CpuFeature scope handling. 
First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.

Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

658ca2f174 Add missing instructions to the IA-32 disasembler 
Added newly added instructions to test-disasem-ia32.cc and implemented the missi
ng ones in the disasembler.

Added some asserts to 8-bit instructions which only work with eax, ebx, ecx and
edx (al, bl, cl and dl).

Removed the loope instruction.

459e4c6b0c Changes to Intel shift functions 
Change name of shifts picking the shift count from cl to sal_cl, shl_cl and shr_cl.

Add special encoding of shift by one for shr which was missing it.

df4f52347b Allow a platform to indicate that some CPU features are always 
available.  We use this to ensure that snapshots on MacOSX can
use SSE2 instructions.  Also clean up and assertify the
handling of things we can't do when we are generating a
snapshot.  Fix a bug in the new serialization tests where
they activated Snapshot::enable() too late after code had been
generated that assumed no snapshots.

c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC. 
- Add the ability for the code to refer to its code object by adding a handle to the code object in the MacroAssembler.

1e42e70021 Use SSE3 instructions - if available - for faster To(U)Int32 
conversion in bit operation stubs. Disable serialization
support by default to allow us to use SSE3 instructions and
faster write barrier code when running without snapshot.

8391b19b07 Refactor the enum RelocMode changing the naming scheme from lower case to 
upper case. Moved it into the RelocInfo class together with the associated
is_xxx functions. Renamed is_xxx to IsXxx in the process.

Removed the exit_js_frame mode as it was no longer used.

Patch Set 2 renames RELOC_MODE_COUNT to NUMBER_OF_MODES and fixes a couple of lint errors.

c42f5829a1 Included mjsunit JavaScript test suite and C++ unit tests. 
In the shell sample don't print the result of executing a script, only
evaluating expressions.

Fixed issue when building samples on Windows using a shared V8
library.  Added visibility option on Linux build which makes the
generated library 18% smaller.

Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.

Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.

Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
