Add a const qualifier to this API call, since this is a member of
MemoryDepChecker and LoopAccessInfo returns an object of this class as a
const.
const MemoryDepChecker &getDepChecker() const { return *DepChecker; }
If one tries to use function as follows:
LAI->getDepChecker().getMaxSafeDepDistBytes()
results in the following error:
passing ‘const llvm::MemoryDepChecker’ as ‘this’ argument discards
qualifiers
