Make tail merging the default, except on powerPC. There was no prior art
...
for a target-dependent default with a command-line override; this way
should be generally usable.

Moved the MachOWriter and ELFWriter out of the Target/* files. Placed the
...
definition of it into the CodeGen library. This is so that a backend doesn't
necessarily add in these writers if it doesn't use them (like in the lli
program).

Another step forward in PPC64 JIT support: we now no-longer need stubs
...
emitted for external globals in PPC64-JIT-PIC mode (which is good because
we didn't handle them before!).
This also fixes a bug handling the picbase delta, which we would get wrong
in some cases.

09fecf9a47
this is an initial patch to switch the ppc64 jit over to working in PIC mode,
...
which allows the code to be above the 2G marker. We still need to JIT emit
dyld stubs to support external, weak, common, etc globals, but that will
happen tomorrow.

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.

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
