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. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
