013860d42e Revert "Reapply change to with/arguments interaction."
Revert this change again.  Somewhat mysteriously we sometimes get empty
contexts that we do not expect in the context chain.

8a9eeaf8da Reapply change to with/arguments interaction.
This is svn r6415 with a bugfix.

The bug was that we can have scopes with 0 heap slots (functions with
such scopes do not need a local context) and scopes with at least
Context::MIN_CONTEXT_SLOTS.  The code generator only allocated a local
context if there were strictly more than Context::MIN_CONTEXT_SLOTS.
Before the change to with/arguments, it was impossible to actually get
a function scope with exactly Context::MIN_CONTEXT_SLOTS because every
such scope included a heap-allocated arguments (and arguments shadow)
slot.

7f43cf0539 Make 'with' mark only variables occurring in the body as used.
Before, we conservatively marked every variable in a scope as used if the
scope contained 'with'.  Instead, just mark the variables occurring in the
body of the with.  This avoids marking 'arguments' as used whenever 'with'
occurs, which incurs an extra performance penalty (a use of arguments is
seen as an instruction to redirect all parameter accesses to the arguments
object).

d131ecf3dd Changed the debugger API to allow only one debug event listener to be registered. The public API now only has SetDebugEventListener instead of AddDebugEventListener and RemoveDebugEventListener.
Moved the registrered debug event listener from the context to a global handle in the Debugger class. Storing it in the context did not make much sense.

Changed a lot of tests to handle the API change.

70dcba4024 Exclude the bit-field bits from string hash codes. String hash codes
are always odd if the bit-field bits are included.

Modified a couple of debugger tests that relied on the ordering of
elements in descriptor arrays.  Descriptor arrays are sorted by
hash-code values, so the order changes if we change the hash code.

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.
