If SME Streaming Mode is enabled, but FP is disabled, we get two
assertion failures within the translator.  Beyond the assertions,
this combination should succeed because we're executing on the
SME co-processor's registers, not the core cpu's AdvSIMD registers.

Patch 2 has a 'bool ret' declaration that needs to move to
the top of its block. Otherwise

Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
