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

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.

* 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.

that were overloaded to work before and after the stackifier runs. With the
new clean world, it is possible to write patterns for these instructions: woo!
This also adds a few simple patterns here and there, though there are a lot
still missing. These should be easy to add though. :)
See the comments under "Floating Point Stack Support" for more details on
the new world order.
This patch as absolutely no effect on the generated code, woo!

This patch adds a -post-link-opts option to llvm-ld which allows an arbitrary
program to optimize bytecode after linking. The program is passed two file
names. The first is the input (linked bytecode) the second is where it must
place its output (presumably after optimizing). If the output file is bytecode,
it is used as a substitute for the input. This will allow things like poolalloc
to be written as a separate program instead of a loadable module or built into
LLVM.

* Add --enable-debug-runtime option, defaults to disabled
* Pass the new config var, DEBUG_RUNTIME, to Makefiles
* Don't use -Wa,-strip-debug if debug-runtime is enabled
