1f13b58b97 Correct bug with left shift on X64 platform from change 4571 (http://code.google.com/p/v8/source/detail?r=4571). Speed up left shift with a constant left hand side on X64 platform. Add unit test for this bug. Remove unused failure target argument from MacroAssembler::SmiShiftLeft and MacroAssembler::SmiShiftLeftConstant.

73fcafd650 Bring back the fisttp instruction on machines with SSE3, but check the
input so we don't have to check the exception flags afterwards.

35b5aab3c7 Fix a bug when shifting left by zero. Ensure that the left operand is
writable (non-aliased) so it can be used for the result in the slow
case.

4d18959446 Avoid a call to the runtime system when doing binary fp ops on ARM
(at the moment only if we do not need to allocate a heap number).
Find a few more oportunities to avoid heap number allocation on IA32.
Add some infrastructure to test coverage of generated ARM code in our
tests.

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.
