For jump instructions that does not include target address as direct
operand, use raw value for that. This is needed for certain powerpc
jump instructions that use target address in a register (such as bctr,
btar, ...).
Before:
ld r12,32088(r12)
mtctr r12
v bctr ffffffffffffca2c
std r2,24(r1)
addis r12,r2,-1
After:
ld r12,32088(r12)
mtctr r12
v bctr
std r2,24(r1)
addis r12,r2,-1
