This patch moves the semantics of 'const' in sloppy mode to match those in strict mode, that is, const makes lexical (let-like) bindings, must have an initializer, and does not create properties of the global object.

This CL simplifies var / const by ensuring the behavior is consistent in itself, and with regular JS semantics; between regular var/const and eval-ed var/const. Legacy const is changed so that a declaration declares a configurable, but non-writable, slot, and the initializer reconfigures it (when possible) to non-configurable non-writable. This avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects. Undefined is used instead.

port r9260 (af9cfd83). Original commit message: We passed this flag around in a lot of places and had differenc call ICs based on it, but never did any real specialization based on its value.

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

Added a few samples and support for building them. The samples include a simple shell that can be used to benchmark and test V8. Changed V8::GetVersion to return the version as a string. Added source for lazily loaded scripts to snapshots and made serialization non-destructive. Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed). Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects. Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events. Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable. Improved performance of converting values to condition flags in generated code. Merged disassembler-{arch} files. git-svn-id: http://v8.googlecode.com/svn/trunk@8 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
