all: add GFNI instructions (#344)

Browse Source 
Adds support for the GFNI "Galois Field New Instructions" instruction set.

These instructions are not included in the Opcodes database, therefore they're
added using the "extras" mechanism introduced in #345.

For simplicity, the loading phase is updated slightly so that AVX-512 form
expansion rules are applied after extras are added to the list. This greatly
reduces the number of forms that have to be specified by hand.

Based on #343
Fixes #335
