15b76de064 Add support for 8 and 16 bit forms of __sync 
builtins on X86.

Change "lock" instructions to be on a separate line.
This is needed to work around a bug in the Darwin
assembler.

2f08e00f01 Update the JIT exception writer to better mimic the codegen exception writer. 
Also skip indirect encoding for platforms that ask for one: we direclty
write an address, not a pointer to the address.

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.

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/
