Issue: https://llvm.org/bugs/show_bug.cgi?id=26720
Fix compile error when building ffmpeg for PowerPC64LE because of some vec_vsx_ld/vec_vsx_st intrinsics are not supported by current clang.
New added intrinsics:
- (vector) {signed|unsigned} {short|char} vec_vsx_ld: (total: 8)
- bool vec_vsx_ld: (total: 1)
- (vector) {signed|unsigned} {short|char} vec_vsx_st: (total: 8)
- bool vec_vsx_st: (total: 1)
Total: 18 intrinsics
