6dd3a5f747 Introduce Simple Analysis interface for loop passes. 
Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

3c756948a5 Allow the INREG parameter attribute to be added to functions. This permits the 
function result to be passed in a register. This implements the GCC regparm
function attribute for llvm by translation to the InReg parameter attribute 
and fixes test/CFrontend/2002-07-30-SubregSetAssertion.c

b0eeb23ce8 The InReg parameter attribute is valid on function results. The llvm-gcc-4.0 
front end converts regparm attribute on the gcc function into InReg attribute 
on the llvm function. This fixes test/CFrontend/2002-07-30-SubrefSetAssertion.c

13fd2f7128 Add detection of __dso_handle presence during configure. Use this information in the 
JITer (short path is added for darwin). This is needed to properly JIT llvm-gcc-4.2-built
binaries, since cxa_atexit is enabled by default on much more targets.

4a3a018844 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.

626679379c 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.

0252aa07ee 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.
