48077e89e9 Remove support for branch hints from the IA32 and X64 assembler.
They were not on by default and should not be needed on modern
platforms.

179aef2b8f VM initialization refactoring.
This patch introduces global once per-process initialization and moves
the OS and CPU setup there. This makes CPU features isolate-independent.

b69591bc0f Require an isolate parameter for most external reference creation to
avoid TLS access in connection with external references.

Make the isolate accessible via the assembler.

Only for ia32 at this point. If this looks OK to you I will port it.

685cae6021 API: Resolve linker issues with using V8 as a DLL
This changes the way the constants kJSObjectType, kFirstNonstringType and kProxyType are made available to the inlined part of the V8 API. This change to fixed constants resolves linker this linker error Windows

error LNK2001: unresolved external symbol "public: static int v8::internal::Internals::kJSObjectType" (?kJSObjectType@Internals@internal@v8@@2HA)

when linking against a V8 DLL.

This change also makes it possible to build all the C++ tests with ENABLE_DEBUGGER_SUPPORT not defined. Now C++ tests run ENABLE_DEBUGGER_SUPPORT not defined, and only the JavaScript tests which tests the debugger fails when ENABLE_DEBUGGER_SUPPORT is not defined.

c7b2af37ba Use direct loop when filling small arrays.
r3995 (http://code.google.com/p/v8/source/detail?r=3995) introduce performance
regression for the case when arrat size is small (think new Array(4)).

It turns out that in those cases rep stos is slower than plain loop (apprently
due to ecx increment, but I didn't check this hypothesis.)  The next thing
to try could be direct jump into right place of long sequence of stos'es.

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.

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.
