[MIPS]question about floating point conditional branch

[Eric Fisher]

Hello,

In mips.md, conditional branch insns are all set with the attribute
value 'branch'. But floating point instructions such as bc1f will
reserve falu unit instead of ialu. So there's a problem when you try
to describe pipeline for 'branch' insns. Define the ialu as the
reservation for all 'branch' insns? Is it OK?
