902453c302 Implement operator<< in terms of basic types rather than [u]int*_t, which is better for portability. There might be some way to factor this all with metaprogramming magic, but I'm not sure how offhand.

6df4ed8bfd Change WriteTypeSymbolic/WriteAsOperand to return void instead of 
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.

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.

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/

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.

312d8de59b add a new raw_ostream class which is an extremely high performance ostream that 
can *only* output data (no seeking, reading, etc).  This is adapted from the
clang "-E outputter", and is roughly 10% faster than stdio on darwin and 30%
(or more) faster than std::ostream.
