[LLVMdev] RegisterScavenging on targets without subregisters
...to it :). A simple bypass (patch attached) does at least not
break 'make check' with x86 and SPU backends. (And fixes the problem
with call.ll-test breaking when the SPU bigframes patch is applied)

[LLVMdev] RegisterScavenging on targets without subregisters
No, I wasn't having a management lobotomy moment. If the target's registers
have no subregisters, SubUsed is false and the assert gets tripped.
Ok, back to the original question: What was the original intent in this code
(lines 186-193 in lib/CodeGen/RegisterScavenging.cpp)?
