Fix sincos errno setting (bug 15467).

Browse Source 
This patch makes sincos set errno to EDOM when passed an infinity,
similarly to sin and cos.

Tested for x86_64, x86, powerpc and mips64.  I don't know if the
architecture-specific implementations for ia64 and m68k might need
corresponding fixes.
