21c4c150 - [LLVM][CodeGen][SVE] Only use unpredicated bfloat instructions when all lanes are in use. (#168387)

[LLVM][CodeGen][SVE] Only use unpredicated bfloat instructions when all lanes are in use. (#168387) While SVE support for exception safe floating point code generation is bare bones we try to ensure inactive lanes remiain inert. I mistakenly broke this rule when adding support for SVE-B16B16 by lowering some bfloat operations of unpacked vectors to unpredicated instructions.
