Prevent some erroneous lit test failures due to unlucky name of working directory

[mbodart]

Summary

Add CHECK-LABEL to several tests which check for the absence of "mov" in llc's assembly output.
Otherwise they will fail if the path name to the LLVM workspace contains "mov", as that name is
emitted in the .file directive.

LGTM with one minor suggestion.

Id prefer this be a little more explicit and have a CHECK-LABEL / CHECK-NOT pair per function.

[mbodart]

Added individual CHECK-LABEL's per function, per review feedback.

Thanks for the cleanup, Mitch. Feel free to commit.
