f5bffa5670 Running with frame pointers prevented debugging, external probes and 
potentially some system calls/exception handling from working.  TOS must always
link to previous frame.  This is a short term workaround until alloca scheme is
reworked.

1409347c13 allow the offset of a preinc'd load to be the low-part of a global. This 
produces this clever code:

_millisecs:
        lis r2, ha16(_Time.1182)
        lwzu r3, lo16(_Time.1182)(r2)
        lwz r2, 4(r2)
        addic r4, r2, 1
        addze r3, r3
        blr

instead of this:

_millisecs:
        lis r2, ha16(_Time.1182)
        la r3, lo16(_Time.1182)(r2)
        lwz r2, lo16(_Time.1182)(r2)
        lwz r3, 4(r3)
        addic r4, r3, 1
        addze r3, r2
        blr

for:

long %millisecs() {
        %tmp = load long* %Time.1182            ; <long> [#uses=1]
        %tmp1 = add long %tmp, 1                ; <long> [#uses=1]
        ret long %tmp1

3a017e8abd Fix a bug in SelectScalarSSELoad. Since the load is wrapped in a 
SCALAR_TO_VECTOR, even if the hasOneUse() check pass we may end up folding
the load into two instructions. Make sure we check the SCALAR_TO_VECTOR
has only one use as well.

1604b6a873 add an initial cut at preinc loads for ppc32. This is broken for ppc64 
(because the 64-bit reg target versions aren't implemented yet), doesn't
support r+r addr modes, and doesn't handle stores, but it works otherwise. :)

This is disabled unless -enable-ppc-preinc is passed to llc for now.

f71921c79d optimize single MBB loops better. In particular, produce: 
LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        jne LBB1_57     #bb207.i
        jmp LBB1_64     #cond_next255.i

intead of:

LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        je LBB1_64      #cond_next255.i
        jmp LBB1_57     #bb207.i

This eliminates a branch per iteration of the loop.  This hurted PPC
particularly, because the extra branch meant another dispatch group for each
iteration of the loop.

7e0f0b2d24 1. Add a pass to fold debug label instructions so a debug info client can detect 
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

a7687f805c Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

4328919c08 Fixed some spiller bugs exposed by the recent two-address code changes. Now 
there may be other def(s) apart from the use&def two-address operand. We need
to check if the register reuse for a use&def operand may conflicts with another
def. Provide a mean to recover from the conflict if it is detected when the
defs are processed later.

8a81e9e264 Split the External and Intrinsic handling into seperate functions. This

makes it clear which parts are hacky (externals) and which parts are good
(call handling).
