fschneider@google.com e7853aab37 Add an explicit push-argument instruction to the IL. 
It is used in ClosureCall and CreateClosure. Refactoring the other call-instruction
will be done in a separate CL.

These instructions do not have their arguments as input operands anymore since they
are really call-arguments passed on the stack.

This allows us to optimize a function with closure calls with SSA. For example:

foo() {
  bar() { return 42; }
  return bar();
}

vegorov@google.com c9e8d9594e Add support for fixed parameters in the register allocator. 
This remove bailout for functions with non-zero number of non-fixed parameters and increases our coverage.

SpillSlot location was renamed into StackSlot location and now allows to address spill slots (positive stack index) and incoming parameters (negative stack index).

Environment was reordered to match order of values on the stack (previously it was inversed).

Correctly reserve spill slots in the prologue of the code. Previously register allocator was allocating spill slots, but generated code did not reserve any space for them on the stack so they might have been overwritten by calls.

Fix off by one in DeoptimizationStub::GenerateCode - we were reserving one slot too many.

Change --optimization-filter flag to use substring search instead of prefix comparison, this is much more useful when VM prefixes function name with a path to the file.

This avoids the complication when collecting the initial live_in sets while iterating forward.

Also simplify the ForwardInstructionIterator class because we have Goto instructions now and
the last instruction of each block does not use the next-link to
indicate a fall-through anymore.

cshapiro@google.com bc6dd1df70 Favor free list allocation to bump pointer allocation. 
This change improves the utilization of the smallest size classes on
benchmarks performing old space allocations including Splay, Box2D,
and Dart2JSCompileAll.

Initial measurements showed that free list allocation was slightly
slower than bump pointer allocation.  Profiling identified that free
list allocation spent most of its time searching for a matching size
class.  To eliminate this overhead, a bitmap index has been added
resulting in no appreciable difference in running time between either
method.
