Fix new IT blocks ARMv8

ARMv8 specifies that an IT block should be followed by only one 16-bit instruction.
* SkFloatToFix is back to a C implementation that mirrors the assembly code.

* S32A_D565_Opaque_neon switched the usage of the temporary 'ip' register to let
the compiler choose what is best in the context of the IT block. And replaced
'keep_dst' by 'ip' where low register or high register does not matter.
