Remove tests for unsupported -sanitize-coverage options.
Remove tests for unsupported -sanitize-coverage options.

LLVM r300769 removed support for these options. There were a series of
earlier changes in Clang (r281432, r300738, r300744, r300767) that probably
ought be have matches changes in Swift.
Tracking that in rdar://problem/31924006
