Krzysztof Parzyszek 1b216a8718 Do not consider subreg defs as reads when computing subrange liveness
Subregister definitions are considered uses for the purpose of tracking
liveness of the whole register. At the same time, when calculating live
interval subranges, subregister defs should not be treated as uses.

; RUN: llc -march=amdgcn < %s | FileCheck %s
; REQUIRES: asserts
;
; This test used to crash with the following assertion:
; llc: include/llvm/ADT/IntervalMap.h:632: unsigned int llvm::IntervalMapImpl::LeafNode<llvm::SlotIndex, llvm::LiveInterval *, 8, llvm::IntervalMapInfo<llvm::SlotIndex> >::insertFrom(unsigned int &, unsigned int, KeyT, KeyT, ValT) [KeyT = llvm::SlotIndex, ValT = llvm::LiveInterval *, N = 8, Traits = llvm::IntervalMapInfo<llvm::SlotIndex>]: Assertion `(i == Size || Traits::stopLess(b, start(i))) && "Overlapping insert"' failed.
;
; This was related to incorrectly calculating subregister live ranges
; (i.e. live interval subranges): subregister defs are not uses for that
; purpose.
;
; Check for a valid output.
