New Revision: 265937

URL: http://llvm.org/viewvc/llvm-project?rev=265937&view=rev
Log:
Do not bind a non-const reference to a rvalue. NFC.

MSVC warns with:
warning C4239: nonstandard extension used: 'initializing': conversion from 'llvm::DebugLoc' to 'llvm::DebugLoc &'
note: A non-const reference may only be bound to an lvalue

Change the reference to a const reference.
