Jim Laskey ae92ce8798 1. Remove condition on delete.
2. Protect and outline createTargetAsmInfo.

3. Misc. kruft.

Chris Lattner 12e97307a1 Completely rearchitect the interface between targets and the pass manager.
This pass:

1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
   output, move all this to common code, and give targets hooks they can
   implement.
3. Commonalize the target population stuff between file emission and JIT
   emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
   paves the way for "fast -O0" stuff in the CFE later, and now LLC could
   lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
   scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
   touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
   which is now orthogonal to the fact that JIT'ing is being done.

Nate Begeman 18f0329cfc Make ppc64 jit kinda work right. About 2/3 of Olden passes with this,
there are clearly some encoding bugs lurking in there somewhere.

Nate Begeman 3cb3921a60 Initial checkin of the Mach-O emitter. There's plenty of fixmes, but it
does emit linkable .o files in very simple cases.

Chris Lattner e1758d4cef Remove what little AIX support we have. It has never been tested and isn't
complete.

Chris Lattner 1ec5e73b32 An overaggressive #ifdef allows a function to fall off the bottom of the
function instead of returning a value.  This sometimes allowed the ppc32 jit
to be used in 64-bit mode.

Chris Lattner f3b5b92e58 Don't pass target name into TargetData anymore, it is never used or needed.
Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

Chris Lattner 0c4aa14deb First baby step towards ppc64 support. This adds a new -march=ppc64 backend
that is currently just like ppc32 :)

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.
This fixes PR 759.

Evan Cheng 73136dfecc - Added option -relocation-model to set relocation model. Valid values include static, pic,
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.

Chris Lattner 88e234dd49 Add a new option to indicate we want the code generator to emit code quickly,
not spending tons of time microoptimizing it.  This is useful for an -O0
style of build.

Chris Lattner c5f9b356af The code generator should work with unreachable blocks. If not, then this
is a bug that should be fixed in the code generator, not papered over with
