Enable optimization suggested by Chris Lattner to not emit reloc stubs for
static global variables whose addresses are taken.  This allows us to

        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.

all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

Add the same optimization that we do loading from fixed alloca slots to
storing to fixed alloca slots.

Write CompilationCallback as an explicit assembly stub to avoid getting GCC's
prolog.

When rewriting the original call instruction, make sure to rewrite it to
call the right address.

Force the intregs ptr into R2 and the FPregs ptr into R3.  This fixes a really
obscure problem where we were doing:

lmw     r3,0(r9)

which is undefined on PPC.  Now we do:

lmw     r3,0(r2)

by force, not relying on the GCC register allocator for luck :)

Implement and document prefix options with arbitrary values including an
= sign. This needed to support -DNAME=value options as pass-through in
llvmc.

Fix bug in emitGEPOperation with large struct-member offsets.

Fix a few more tests by encoding the extsb and other XForm11 instructions
correctly.

Fix the encoding of ORi and other DForm4 instructions.  This brings us to
36/42 SingleSource/UnitTests passing!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18199 91177308-0d34-0410-b5e6-96231b3b80d8

Calls do not need a MovPCtoLR instruction

Get constant pools working.  This fixes even more programs, allowing us to
pass 24/42 in UnitTests (up from 20).

Forced branches to be first to be scheduled.

Rewrite branches more closely to correct.  This makes more stuff pass, and
stops the infinite loops!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18194 91177308-0d34-0410-b5e6-96231b3b80d8

Branch instructions explicitly represent CRx in them. bEcause of this, encode
them explicitly as well.
