Vedant Kumar 65b0d4df20 [DebugInfo] Create merged locations for instructions other than calls 
This lifts a restriction on DILocation::getMergedLocation(), allowing it
to create merged locations for instructions other than calls.

Instruction::applyMergedLocation() now defaults to creating merged
locations for all instructions.

The default behavior of getMergedLocation() is unchanged: callers which
invoke it directly are unaffected.

This change will enable a follow-up Mem2Reg fix which improves crash
reporting.

Paul Robinson 383c5c228f Merge DebugLoc on combined stores; in this case, when combining stores 
from the end of two blocks, merge instead of arbitrarily picking one.
