v8/test/mjsunit/debug-changebreakpoint.js
christian.plesner.hansen 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.
