This patch extends variable vec_insert to all 32bit VSX targets including
Power7{BE} {32,64}, Power8{BE}{32, 64}, Power8{LE}{64}, Power9{LE}{64}, all
tested  pass for power testcases, though AIX is not tested yet. @Segher, please
review this one instead of the previous that disables 32 bit variable
vec_insert, thanks.

For Altivec targets like power5/6/G4/G5, take the previous "vector store/scalar
store/vector load" code path.
