cc619a34ef Remove list copy constructor (for which there was no corresponding 
assignment operator) and add an AddAll method to lists instead.

ef85ba46b0 First round of size reduction for JumpTargets. Reduce their size by 
two words: there is no reason to keep a pointer to the current code
generator and macro assembler in the JumpTarget.

f4778b007f Reduce the memory used by frame elements from two words to one by 
encoding the values in one word and by using an indirection table for
handles.

This reduces compilation time by roughly 10% and we should be able to make the slow case equality checking of frame elements faster as well.

83f2c1968f Streamline JumpTarget::ComputeEntryFrame by removing the separate loop 
that sets the static type on elements in the entry frame.  Instead set
the static type as early as possible when computing elements.

Because the elements are shared with the reaching frames, this has the
side effect of sometimes changing the static type of reaching frame
elements.  They will be changed anyway in VirtualFrame::PrepareMergeTo
immediately after, so this is safe.

undetermined elements) and another pass to set the frame's register

06860982a9 Clean up return statements in the code generator by explicitly 
counting the reference to the return value and passing it to the
return label.  This requires threading it through try/catch and
try/finally.  The return value is loaded into eax more lazily than
before.

Also, perform some related refactoring of jump targets.

cd296924b6 Add a copied flag to virtual frame elements that tells if a copy has 
been made of the element.  Set it when copying an element, clear it
when writing to an element marked copied and discovering that it is
not copied.

The copied flags on entry frames are exact.  Preparing a frame for
merging set the copied flags to be exact (to increase the likelihood
of matching the entry frame or another frame).
