 sincos: Implement sincos[f]_stret

 Builds with 10.9+ SDKs expect these functions as part of an improved
 internal interface, but they don't become available until 10.9.
 Builds targeting 10.6 or earlier don't use them, but we don't worry
 about that.

 We don't try to do anything fancy - this just creates a compatible
 interface to the two-call approach.

 TESTED:
 Tested on 10.4-10.5 ppc, 10.5-10.6 ppc (i386 Rosetta), 10.4-10.6 i386,
 10.5-12.x x86_64, and 11.x-14.x arm64.  Tested against all 10.4-14.x
 SDKs, using the headerinfo manual test (from a subsequent commit).
 All target/SDK combinations where the SDK supports the CPU
 architecture work correctly, including all SDKs on Intel
 architectures.  Only 10.4-10.6 SDKs support ppc, and only 11.x+ SDKs
 support arm64.
