Sanjay Patel d2153694e0 Handle sqrt() shrinking in SimplifyLibCalls like any other call ... This patch removes a chunk of special case logic for folding (float)sqrt((double)x) -> sqrtf(x) in InstCombineCasts and handles it in the mainstream path of SimplifyLibCalls. No functional change intended, but I loosened the restriction on the existing sqrt testcases to allow for this optimization even without unsafe-fp-math because that's the existing behavior. I also added a missing test case for not shrinking the llvm.sqrt.f64 intrinsic in case the result is used as a double.
