[LLVMdev] anti-dependency breaking and mask/shift dependencies
On PowerPC (at least versions which predate the mfocrf instruction),
while there are multiple independent condition registers, the only way
to move those registers into a general-purpose register is to use mfcr,
which transfers all of the (concatenated) condition registers into one
general purpose register, followed by a mask/shift operation to extract...
