Before computing reaching definitions, the set of all definitions in a function must be collected and they must be numbered. Have the flow graph builder collect definitions for stack-allocated variables into a list, and implicitly number them with their list index.

The fast case of looking up the string convertion of the smi did not handle the case where left/reghe operands could be in eax/edx instead of edx/eax which is the default. Also got rid of creating an internal frame for calling string and instead patched the argument on the stack and performed a tail call.

Added zone-inl.h to jsregexp.h since it relies on calling new ZoneList which again relies on calling the static new method on Zone (defined in zone-inl.h but declared in zone.h).

Remove messages.h from v8.h and include it explicitly in only the few places it is needed. Many files relied on getting handles-inl.h implicitly from messages.h through v8.h, so include handles-inl.h explicitly in v8.h instead. Remove zone-inl.h from header files where it is not needed, can be replaced by a forward declaration, or can be replaced by zone.h (specifically, factory.h and heap.h). Include zone.h or zone-inl.h in header files where it was implicitly included via heap.h or factory.h. Prefer zone.h over zone-inl.h in header files where possible by including zone-inl.h in .cc files.

A variable usage analysis pass was run on toplevel and lazily-compiled code but never used. Remove this pass and the data structures it builds. The representation of variable usage for Variables has been changed from a struct containing a (weighted) count of reads and writes to a simple flag. VariableProxies are always used, as before. The unused "object uses" is removed. Review URL: http://codereview.chromium.org/669270 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@4052 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

The flow graph is built by walking the AST. Edges are labeled with instructions (AST nodes). Normal nodes have a single predecessor edge and a single (labeled) successor edge. Branch nodes are explicit, they have a single predecessor edge and a pair of (unlabeled) successor edges. Merge nodes are explicit, they have a pair of predecessor edges and a single (unlabeled) successor edge. There is a distinguished (normal) entry node and a distinguished (special) exit node with arbitrarily many predecessor edges and no successor edges. The graph is intended to support graph-based analysis and transformation.

When Array(0) or new Array(0) is handled by the generated code it is handled by the same code as Array() and new Array(). For this to work the stack is tweaked to remove the argument of value 0. However the argc was still passed as 1 if a call to the runtime system was made. When the stack is tweaked argc is also changed to 0.
