Sanjay Patel c81450e29b [Driver, CodeGen] rename options to disable an FP cast optimization
As suggested in the post-commit thread for rL331056, we should match these 
clang options with the established vocabulary of the corresponding sanitizer
option. Also, the use of 'strict' is well-known for these kinds of knobs, 
and we can improve the descriptive text in the docs.

So this intends to match the logic of D46135 but only change the words.
Matching LLVM commit to match this spelling of the attribute to follow shortly.
