Only handles when x is int32 and y is int32 constant. BUG=v8:2038 Currently implemented by imul (not fpmul). x86 and x64 algorithm differs a bit. x86 implementation is kind of cumbersome, but I couldn't think of better ways.

Unbreak bleeding_edge by getting the Parser to work with a CompilationInfo instead of a Handle<Script> and a Zone. This should have been fixed in the initial patch itself but escaped my attention.

The CompilationInfo record now saves a Zone, and the compiler pipeline allocates memory from the Zone in the CompilationInfo. Before compiling a function, we create a Zone on the stack and save a pointer to that Zone to the CompilationInfo; which then gets picked up and allocated from.

with more JS code that is loaded into the VM before writing the snapshot. Get rid of the hard coded limit on the partial snapshot cache size. This change disables most of the serializer tests for the snapshot build of the VM: It's getting too complicated to support both booting from a snapshot and then creating a new snapshot from the same VM or loading more code with another snapshot in the same VM.

This changes the compiler to be more aggressive about lazy compilation of closures with non-trivial outer context. Compilation can only be triggered with a valid outer context now. One exception is the debugger, which can request compilation of arbitrary shared code, but it ensures to trigger compilation only at points where no context is needed. This relands r11782, r11783, r11790 and a minor fix.
