HLSL 202x inherits from C++11, which generates additional loop hint information
for loops that must progress. Since HLSL 202x is going to be the default for
Clang we want to make sure all our tests pass with it.

Subject: [PATCH] [NFC] [HLSL] Update test for HLSL 202x
HLSL 202x inherits from C++11, which generates additional loop hint
information for loops that must progress. Since HLSL 202x is going to
be the default for Clang we want to make sure all our tests pass with
