Target Independent Code Generator Improvements
----------------------------------------------
Stack Coloring - We have implemented a new optimization pass to merge stack
objects which are used in disjoin areas of the code. This optimization reduces
the required stack space significantly, in cases where it is clear to the
optimizer that the stack slot is not shared. We use the lifetime markers to
tell the codegen that a certain alloca is used within a region.
We now merge consecutive loads and stores.
We have put a significant amount of work into the code generator
infrastructure, which allows us to implement more aggressive algorithms and
make it run faster:

We have added a new target independent VLIW packetizer based on the DFA
infrastructure to group machine instructions into bundles.
