[PowerPC] Add VSX builtins for vec_div
This patch adds builtin support for xvdivdp and xvdivsp, along with a new test case. The builtins are accessed using vec_div in altivec.h. Builtins are listed (mostly) alphabetically there, so inserting these changed the line numbers for deprecation warnings tested in test/Headers/altivec-intrin.c. There is a companion patch for LLVM. llvm-svn: 221984
