This fixes failures on configurations that don't have one or the
other targets enabled.

This allows the 64-bit forms to use+def RSP instead of ESP. This
doesn't fix any real bugs today, but it is more precise and it
makes the debug dumps on x86-64 look more consistent.

Also, add some comments describing the CALL instructions' physreg
operand uses and defs.

pointer bitcasts and GEP's", and centralize the
logic in Value::getUnderlyingObject.  The
difference with stripPointerCasts is that
stripPointerCasts only strips GEPs if all
indices are zero, while getUnderlyingObject
strips GEPs no matter what the indices are.

 - So far this works fairly well for me for building applications
   using clang as a gcc substitute. If you are using ccc for a
   different purpose and this is a problem, speak up! Note you can
   also use CCC_NATIVE=0 to disable.

 - Also, turn CCC_ECHO off as default.

 - Also, pass through -Wl, to linker.

collisions.
 - Provide CodeGenModule::CreateRuntimeFunction which guarantees that
   the function it creates will have the provided name in the final
   module. This allows the runtime to have its functions protected
   from declarations of the same name in the source code.

 - One could argue that this is a reason to abuse the llvm::Module
   namespace for dealing with function redeclarations. However, that
   approach seems conceptually flawed to me. This one also happens to
   be somewhat more efficient.

No functionality change.

Use this updated interface when invalidating arguments passed by reference; the type of symbol is of the object passed by reference, not the reference itself.

One might anticipate that at some point I will just break down and go
through the man page. That seems a little too obvious.

Fix a simple error in renumbering kill markaers, that took an inordinant amount of time to track down.

- Testcase for r56885.

`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero"
instead of "__bzero" on Darwin10+. This arguably violates the meaning of this
flag, but is currently sufficient. The meaning of this flag should become more
specific over time.

 - More straightforward, e.g. -E should always imply action =
   'preprocess' (I think).
 - Pass another option through for OS X.
