eb8e1d9d0e Change test script to make it easy to run crankshaft tests on ARM and 
x64 where crankshaft is not the default. Add ability to add custom
expectations for running in this special crankshaft mode.

The expectations are not updated in this change. There are a couple of
bugs that I would like to fix before doing that. Otherwise the lists
will be very long. :)

Make checks.h not depend on flags.h or global.h (or anything else except
include/v8stdint.h). Only checks.cc has the dependencies (so another
implementation of checks.cc can be provided by the preparser).
Now files depending on checks.h (using ASSERT macros) can include it
directly without depending on all of v8.

e6b33bd20b Support profiling based on linux kernel performance events. 
Since 2.6.31 perf_events interface has been available in the
kernel. There's a nice tool called "perf" (linux-2.6/tools/perf) that
uses this interface and provides capabilities similar to oprofile. The
simplest form of its usage is just dumping the raw log (trace) of
events generated by the kernel. In this patch I'm adding a script
(tools/ll_prof.py) to build profiles based on perf trace and our code
log. All the heavy-lifting is done by perf. Compared to oprofile agent
this approach does not require recompilation and supports code moving
garbage collections.

Expected usage is documented in the ll_prof's help. Basically one
should run V8 under perf passing --ll-prof flag and then the produced
logs can be analyzed by tools/ll_prof.py.

The new --ll-prof flag enables logging of generated code object
locations and names (like --log-code), and also of their bodies, which
can be later disassembled and annotated by the script.

e9b5d7855b Allow build-time selection between ia32 and x86_64 in the GYP/Xcode Mac 
Chromium build.

v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the
proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as
the V8_HOST_ARCH_* macro when it detects that no target macro is currently
defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files.
#ifdef guards in each of these target-specific source files prevent their
compilation when the associated target is not selected. For completeness,
these #ifdef guards are also provided for the arm and mips .cc files.

BUG=706

fa7c92eaf5 First step towards making JumpTarget work on ARM. Instead 
of having a list of virtual frame pointers in the jump
target we have one virtual frame, which is the frame that
all have to merge to to branch to that frame.  The virtual
frame in the JumpTarget is inside the JumpTarget, rather than
being an allocated object that is pointed to.  Unfortunately
this means that the JumpTarget class has to be able to see
the size of a VirtualFrame object to compile, which in turn
lead to a major reorganization of related .h files.  The
actual change of functionality in this change is intended
to be minimal (we now assert that the virtual frames match
when using JumpTarget instead of just assuming that they do).

The V8 GYP file now uses its own target architecture. It default to the standard target_arch, but can be set to a separate value. E.g. using

  export GYP_DEFINES="target_arch=ia32 v8_target_arch=arm"

makes it possible to have the V8 ARM simulator be used in a IA32 build.

Added some checking of supported host/target architecture combinations.

This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

dbe99e405a Introduce number type information in the virtual frame. 
Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

e51a05f338 Fix issue 597: builtins and stubs are missing in profiler log when using snapshots. 
After this fix, profiles of non-snapshotted VMs are now equivalent to

and mksnapshot's log is given to the tick processor script.)

BUG=597
