Duncan P. N. Exon Smith 51ce2b263f Hexagon: Avoid dereferencing end() in HexagonCopyToCombine::findPairable 
Check for end() before skipping through debug values.  This avoids
dereferencing end() when the instruction is the final one in the basic
block.  (It still assumes that a debug value will not be the final
instruction in the basic block.  No tests seemed to violate that.)

Many Hexagon tests trigger this, but they happen to magically pass right
now.  I found this because WIP patches for PR26753 convert them into
crashes.
