Sanjay Patel 86d24f1668 [ValueTracking] readonly (const) is a requirement for converting sqrt to llvm.sqrt; nnan is not 
As discussed in D39204, this is effectively a revert of rL265521 which required nnan 
to vectorize sqrt libcalls based on the old LangRef definition of llvm.sqrt. Now that
the definition has been updated so the libcall and intrinsic have the same semantics
apart from potentially setting errno, we can remove the nnan requirement.

We have the right check to know that errno is not set:

if (!ICS.onlyReadsMemory())

...ahead of the switch.

This will solve https://bugs.llvm.org/show_bug.cgi?id=27435 assuming that's being 
built for a target with -fno-math-errno.
