#7861: altivec compilation broken starting with gcc 8.3

-------------------------------------+-------------------------------------
Starting with gcc 8.3, it is not allowed to use typedefs with the altivec
vector keyword when this keyword is builtin (e.g. `vector uint32_t`). It
is necessary to either use the base type (like, `vector unsigned int`) or
use the `__vector` gcc extension (like, `__vector uint32_t`).
There's a bunch of recently-added code violating this, such as
https://github.com/FFmpeg/FFmpeg/commit/8dd9df9ecd258cff84cef559f16e682949e78e38
#diff-2177d684d44cafdce18adf016216b747
This breaks build on powerpc; see gcc documentation for reference
https://gcc.gnu.org/onlinedocs/gcc-8.3.0/gcc/PowerPC-AltiVec_002fVSX-
Built-in-Functions.html
Not sure if other components are affected.
