[PowerPC] Disable CTR loops optimization for soft float operations

This patch prevents CTR loops optimization when using soft float operations
inside loop body. Soft float operations use function calls, but function
calls are not allowed inside CTR optimized loops.

Patch by Aleksandar Beserminji.
