   TargetMachine subclasses' constructor calls.

 - This abuses TargetMachineRegistry's constructor for now, this will get
   cleaned up in time.

cleanup, removed some #includes and moved Object Code Emitter out-of-line.

 - This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

require RIP-relative addressing and use it to fix a bug
in X86FastISel in x86-64 PIC mode, where it was trying to
use base/index registers with RIP-relative addresses. This
fixes a bunch of x86-64 testsuite failures.

Move X86 assembler printers into separate directory. This allows JIT-only users not to link it in (use 'x86codegen' llvm-config arg for this)

This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

FunctionPassManager or PassManager, or even with a custom new

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.

TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

llvm-svn: 28238

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.
