Dan Gohman eabd647cd5 Change target-specific classes to use more precise static types.
This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Dan Gohman 24570836b2 Use PassManagerBase instead of FunctionPassManager for functions
that merely add passes. This allows them to be used with either
FunctionPassManager or PassManager, or even with a custom new
kind of pass manager.

Bill Wendling 59889ae93f Added new method to add a "simple" code emitter. That is, to only add
the code emitter and not set variables.

Andrew Lenharth a6bbf33cbf Jimptables working again on alpha.
As a bonus, use the GOT node instead of the AlphaISD::GOT for internal stuff.

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.

Owen Anderson 8c2c1e90c4 Refactor a bunch of includes so that TargetMachine.h doesn't have to include
TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

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.

Chris Lattner 6f95ab7abb Eliminate IntrinsicLowering from TargetMachine.
Make the CBE and V9 backends create their own, since they're the only ones that use it.

Chris Lattner b28f214033 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 -O0style of build.
