Teach SDISel to combine fsin / fcos into a fsincos node if the following
conditions are met: 1. They share the same operand and are in the same BB. 2. Both outputs are used. 3. The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX. Also added an additional optimization for x86_64 Mac OSX by using an alternative entry point __sincos_stret which returns the two results in xmm0 / xmm1. rdar://13087969 PR13204 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173755 91177308-0d34-0410-b5e6-96231b3b80d8
