[mips] Add an IR transformation pass that optimizes calls to sqrt. The pass emits a call to sqrt that has attribute "read-none". This call will be converted to an ISD::FSQRT node during DAG construction, which will turn into a mips native sqrt instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183802 91177308-0d34-0410-b5e6-96231b3b80d8

Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8
