ARM: correctly decode VFP instructions following unpredictable t2IT
When the condition code for an IT instruction is "AL" we get strange "15"
predicates on subsequent instructions. These are dealt with for most
instructions by treating them as "ARMCC::AL", but VFP takes a different path
which didn't have this code.
