889cbe55b8 Fix a bug in the regexp caching. Also add a few more places to 
cache.  We now cache most of the places where Opera cache and
one or two where they do not cache for some reason.  Since
these optimizations aren't necessarily useful on real code we
may remove them if and when the Dromaeo website makes the
benchmarks harder to game.

3ca9367341 Fix bug in propagation of type information into registers. 
The number type information of results has to be also copied when
calling ToRegister with a fixed register as destination.

Also fix an unbound label and a missing CpuFeatures scope.

IsPrimitive reflects that an expression's value is known statically to

Null, Boolean, String, or Number).

The type conversions ToPrimitive, ToNumber, ToInteger, ToInt32,
ToUInt32, ToUint16, ToString, or ToObject cannot invoke user code for
primitive input values.  ToObject throws a TypeError if its input is
Undefined or Null.

d6e08a41f6 Probe number dictionaries in generated code on ia32. 
With my previous change to limit memory for object literals, we get more slow-case elements and this makes up for the slowdown when loading from those slow-case elements.

The most complicated part here is the computation of the integer hash code.  We might want to simplify the integer hash function.

cb1f817f77 Initialize reaching definitions state for all flow graph nodes. 
Reaching definitions in (RD_in) is initially empty for all nodes.  Gen
and kill sets are computed.  AST node numbers are used for nodes to
refer to their definition number.

Also: two small changes to flow graph printing.  Children of branch
nodes are visited in right-to-left order when performing depth first
search.  Instructions are numbered locally within blocks so as to not
destroy AST node number before printing (it's useful to print the
definition).
