Subject: [PATCH] Rename a flang test case

On Windows and macOS, the filesystem is case insensitive, and these files
interfere with each other. Reading through, the case of the file extension
is part of the test. I've altered the rest of the name instead.

(cherry picked from commit 6c0a160c2d33e54aecf1538bf7c85d8da92051be)
(cherry picked from commit 0a1b1118cfd0716d1373438528b8e80914b436dd)
