Enable optimization suggested by Chris Lattner to not emit reloc stubs for
static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

Emit relocations for the global variable using instructions.  This gets us
LA, LOADHiAddr, CALLpcrel, and MovePCtoLR working, though the constant pool
probably is not right.

Allow configuration files to be themselves configured and found in the
OBJ dir instead of only in the SRC dir.

Move JITInfo from PPCTM to PPC32TM

Do not provide the non-specialized PowerPCJITInfo object, it is pretty useless.
Instead, let derived classes provide specialized ones.

LA is really addi.  Be consistent with operand ordering to avoid confusing the code emitter

Changed the CreateCodeToLoadConst function to preserve SSA form. This basically means adding extra tmp instructions for intermediate values.

Comment out a couple of unused instructions.

Do not push two return addresses on the stack when we call external functions who have their addresses taken.  This fixes test-call.ll

Remove some dead vars and some useless namespacification

Implement a disgusting hack to work around broken machine code emission of
the RDCCR instruction.  This fixes a bunch of programs with the JIT.

Fixed a bug where I was trying to ModuloSchedule a loop with no instructions but a terminator.
Fixed a bug in the schedule generation that was always using the start cycle.
