Instead of adding copyfromreg's to handle physical definitions. Now isel can
simply specify them as results and let scheduledag handle them. That
is, instead of
SDOperand Flag = DAG.getTargetNode(Opc, MVT::i32, MVT::Flag, ...)
SDOperand Result = DAG.getCopyFromReg(Chain, X86::EAX, MVT::i32, Flag)

Just write:
SDOperand Result = DAG.getTargetNode(Opc, MVT::i32, MVT::i32, ...)

And let scheduledag emit the move from X86::EAX to a virtual register.

VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control.

This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.

Updates to the VStudio project files:

1. Switch from VStudio 2k3 to VStudio 2k5

2. All pdb files now will be placed as $(OutputDir)/$(ProjectName).pdb.  This puts them alongside the
binaries with the same base name as the binary.  If you need to copy the results of your llvm build
into another project's tree, this will simplify that process.

3. Recent files added to the tree were added to the proejects within the VStudio project

4. Project build dependency order fixed so that the build can take place in one pass.  A generated
file was not being built at the correct time, causing a build error in about half the projects until
the build was run a second time.

Note you will need flex and bison installed an in your path in order to build properly.

Allow SmallPtrSet to hold pointers to const data.

Re-apply 40504, but with a fix for the segfault it caused in oggenc:
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.
