core: workaround old gcc vec_mul{e,o} (Issue #15506)

ISA 2.07 (aka POWER8) effectively extended the expanding multiply
operation to word types. The altivec intrinsics prior to gcc 8 did
not get the update.

Workaround this deficiency similar to other fixes.

This was exposed by commit 33fb253a66275abaa5060ef318c9a5cc87c5fd6e
which leverages the int -> dword expanding multiply.

This fixes Issue #15506
