293dfe59a5 R600/SI: Disable subreg liveness 
This is temporary while we try to fix a crash in the register coalescer.

a065cf13cd RegisterCoalescer: Fix valuesIdentical() in some subrange merge cases. 
I got confused and assumed SrcIdx/DstIdx of the CoalescerPair is a
subregister index in SrcReg/DstReg, but they are actually subregister
indices of the coalesced register that get you back to SrcReg/DstReg
when applied.

Fixed the bug, improved comments and simplified code accordingly.

Testcase by Tom Stellard!
