a1757d1d91 Start using the new and improve interface to FunctionType arguments

cb8c4b9d1b Improve encapsulation in the FunctionType class, by adding param_(iterator/begin/end) 
members, and eliminating the getParamTypes() method, and the associated typedef.

76292e7fcc Instead of searching the entire type graph for a type to determine if it 
contains the type we are looking for, just search the immediately used types.
We can only do this because we keep the "current" type in the nesting level
as we decrement upreferences.

This change speeds up the testcase in PR224 from 50.4s to 22.08s, not
too shabby.

645f8fb4e5 Upreferences are always OpaqueTypes, meaning that it is impossible for a non-abstract 
type from containing one.  This speeds up the asmparser on the testcase in PR224 from
61->50s.

95c21b04da Another nice speedup for the register allocator. This time, we replace 
the Virt2PhysRegMap std::map with an std::vector.  This speeds up the
register allocator another (almost) 40%, from .72->.45s in a release build
of LLC on 253.perlbmk.

9fb6056f1f Ugh, perform an optimization that GCC should be able to do itself. This 
speeds up livevar from .48/.32s -> .45/.31s in LLC on perlbmk

b665065e6d Only do stuff for the REAL number of physical registers we have, not 1024. 
This speeds up live variables a lot, from .60/.39s -> .47/.26s in LLC, for
the first/second pass respectively.

c49e77cecd Change the PhysRegsUsed map into a dense array. Seeing that this is a mapping 
from physical registers, and they are always dense, it makes sense to not have
a ton of RBtree overhead.  This change speeds up regalloclocal about ~30% on
253.perlbmk, from .35s -> .27s in the JIT (in LLC, it goes from .74 -> .55).

Now live variable analysis is the slowest codegen pass.  Of course it doesn't
help that we have to run it twice, because regalloclocal doesn't update it,
but even if it did it would be the slowest pass (now it's just the 2x slowest
pass :(

b771939ef3 Two problems with these lines of code: 
1. The "work" was not in the assert, so it was punishing the optimized release
 2. getNamedFunction is _very_ expensive in large programs.  It is not designed
    to be used like this, and was taking 7% of the execution time of the code
    generator on perlbmk.

Since the assert "can never fail", I'm just killing it.

cc1376078c Instead of callign removeTriviallyDeadNodes on the global graph every time 
removeDeadNodes is called, only call it at the end of the pass being run.
This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is
pretty big.  This is only possible because of the automatic garbage
collection done on forwarding nodes.

32a3eb0b88 Substantially improve the DSA code by removing 'forwarding' nodes from 
DSGraphs while they are forwarding.  When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted.  This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

aaa095c8f4 One of the 'annoying' things about ilists is that the iterators don't behave 
quite the same as for non-intrusive lists of pointers to nodes.  To support
transitioning code bases, add a new 'compatibility' iterator.
