gallivm/ppc64le: allow environmental control of Altivec code generation
In check_os_altivec_support(), allow control of Altivec (first PPC vector
instruction set) code generation via a new environmental control,
GALLIVM_ALTIVEC, which is expected to take on a value of 1 or 0.
The default is to enable Altivec code generation.
This environmental control of Altivec code generation is initially
available only #ifdef DEBUG.
