9e4fbb45c1 One Zone per CompilationInfo. 
The CompilationInfo record now saves a Zone, and the compiler pipeline
allocates memory from the Zone in the CompilationInfo.  Before
compiling a function, we create a Zone on the stack and save a pointer
to that Zone to the CompilationInfo; which then gets picked up and
allocated from.

By passing around a Zone object explicitly we no longer need to do a
TLS access at the sites that allocate memory from the current Zone.

We should only mark a string as an array index if we can store the entire value
of the number in the hash field. We sometimes failed to reject larger numbers.

53fbd5932a Perform string add in generated code on IA-32 platforms 
This adds a code stub which can do most of what Heap::AllocateConsString can do. It bails out if the result cannot fit in new space or if the result is a short (flat) string and one argument is an ascii string and the other a two byte string. It also bails out if adding two one character strings as Heap::AllocateConsString has special handling of this utilizing the symbol table. The stub is used both for the binary add operation and for StringAdd calls from runtime JavaScript files. Extended the string add test to cover all sizes of flat result stings.

Set warning level to /W3 and change implicit conversions from size_t

a special strlen replacement that returns int.

- String traversal test data (now in a zone)
 - Debug message thread (now joined on exit)
 - Threading test threads (now joined on exit)
 - Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8.  Good times.

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.
