36e9a0b3 - [AArch64][GlobalISel] Correct instructions for 64bit fneg constant vectors. (#166537)

[AArch64][GlobalISel] Correct instructions for 64bit fneg constant vectors. (#166537) This code was assuming that the vectors were 128bit. Add handling for 64bit vectors. Some of the tests do not apply yet due to not matching non-splat vectors. Fixes #166400
