[MIR] Fix vreg flag vector memory leak (#112479)
A fix-it patch for dbfca24 #110228.
No need for a container. This allows 8 flags for a register.
The virtual register flags vector had a memory leak because the vector's
memory is not freed.
The `BumpPtrAllocator` handles the deallocation and missed calling the
`std::vector<uint8_t> Flags` destructor.
