Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Nate Begeman 6e6514c47e Several fixes and enhancements to the PPC32 backend.
1. Fix an illegal argument to getClassB when deciding whether or not to
   sign extend a byte load.

2. Initial addition of isLoad and isStore flags to the instruction .td file
   for eventual use in a scheduler.

3. Rewrite of how constants are handled in emitSimpleBinaryOperation so
   that we can emit the PowerPC shifted immediate instructions far more
   often.  This allows us to emit the following code:

int foo(int x) { return x | 0x00F0000; }

_foo:
.LBB_foo_0:     ; entry
        ; IMPLICIT_DEF
        oris r3, r3, 15
        blr

Misha Brukman 6b17bf7193 s/ISel/PPC64ISel/ to have unique class names for debugging via gdb because the
C++ front-end in gcc does not mangle classes in anonymous namespaces correctly.

Reid Spencer 7c16caa336 Changes For Bug 352
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Misha Brukman 170943a795 Stack space for argument passing is 32 regardless of 32- vs. 64-bit arch.
Thanks to Nate Begeman for pointing this out.
