Subject: [PATCH] [AArch64] Make sure to load the full destination register on
 float instructions.

With the float instructions that only affect the lower 64bits of the destination register, we need to make sure to load the full 128bit register.
This ensures that we aren't saving garbage in to the top 64bits.
