c6e031668d Reid had to call this class "slot machine" out of some strange reference 
to the gambling device.  Name it something more meaningful.

39bb486001 Resurrect some ancient code to add spill ranges without attempting folding, remat, or splitting. This code has been updated to current APIs 
in so far as it compiles and, in theory, works, but does not take advantage of recent advancements.  For instance, it could be improved by using
MachineRegisterInfo::use_iterator.

12569b3697 Don't hoist instructions that have implicit uses or defines. Before, it was 
hoisting out some "test" and "cmp" instructions. This was obvious badness.

2cc861a6c1 Rename some GC classes so that their roll will hopefully be clearer. 
In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:

  Collector               -> GCStrategy
  CollectorMetadata       -> GCFunctionInfo
  CollectorModuleMetadata -> GCModuleInfo
  CollectorRegistry       -> GCRegistry
  Function::getCollector  -> getGC (setGC, hasGC, clearGC)

Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.

e1e9213f95 Make it compile on VC2005: 
- update VC projects.
- Add an overload to llvm::Stream for <<, since std::hex and std::dec have type std::ios_base& (*)(std::ios_base&) in VC++. (templating the function don't work, due to ambiguities)
- add ../ on several include in X86/AsmPrinter/

205be593b8 Xor'ing both sides of icmp by sign-bit is equivalent to swapping signedness of 
the predicate.

Also, make this optz'n apply in more cases where it's safe to do so.

661710bbd1 avoid an extraneous std::string construction

c0610874cc Rework the routines that convert AP[S]Int into a string. Now, instead of 
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.
