History
Bill Wendling b19a5e9be6 Modify how the prologue encoded the "move" information for the FDE. GCC 
generates a sequence similar to this:

__Z4funci:
LFB2:
        mflr r0
LCFI0:
        stmw r30,-8(r1)
LCFI1:
        stw r0,8(r1)
LCFI2:
        stwu r1,-80(r1)
LCFI3:
        mr r30,r1
LCFI4:

where LCFI3 and LCFI4 are used by the FDE to indicate what the FP, LR, and other
things are. We generated something more like this:

Leh_func_begin1:
        mflr r0
        stw r31, 20(r1)
        stw r0, 8(r1)
Llabel1:
        stwu r1, -80(r1)
Llabel2:
        mr r31, r1

Note that we are missing the "mr" instruction. This patch makes it more like the
GCC output.
