the rough idea sketched out in http://nondot.org/sabre/LLVMNotes/CallGraphClass.txt,
allowing new spiffy implementations of the callgraph interface to be built.

Many thanks to Saem Ghani for contributing this!

i.e. r1/r12/rp are saved/restored regardless of scheduling/luck

TODO: calls to external symbols, indirect (function descriptor) calls,
      performance (we're being paranoid right now)

BUG: the code for handling calls to vararg functions breaks if FP
args are passed (this will make printf() go haywire so a bunch of
tests will fail)

BUG: this seems to trigger some legalize nastiness

SPARCv8. (we copy sparcv8's workaround for tablegen not being nice about
ISD::CALL/TAILCALL)

Move the system dependent portion to lib/System/*/Alarm.inc. This makes the
SlowOperationInformer platform independent.

dependent portion of the lib/Support/SlowOperationTimer code into the
lib/System implementation where it can be ported to different platforms.

  either an operand or a result.
* Fixed some more flag / chain bugs.

* Make it possible to pass a fourth argument to the CHECK_PROGRAM_SANITY
  macro that controls whether a non-sane program generates an error or
  a warning.

* Changed the -rpath option from cl::opt to cl::list
* Changed the interface to GenerateNative to take a std::vector<std::string>
  instead of just a std::string
* Changed GenerateNative to generate multiple -Wl,-rpath, options to be
  passed to gcc.

1. When srcdir == objdir have "spotless" say that it isn't supported in
   that mode rather than just let make say "no such target"
2. Minor doc cleanups
3. Fix the double rebuild problem with yacc files. A missing dependency
   caused parallel builds to skip building the .cpp file after the .cpp
   file was regenerated by bison.
