- Flush before the queued draws would decode more than VERTEX_BUFFER_MAX
vertices. The batch was limited by index count, which doesn't bound a
sparse index range, and DecodeVerts silently stopped while DecodeInds
still emitted indices for the undecoded draws.
- Give TestBoundingBox its own scratch buffer. It used offsets in decoded_,
which can hold decoded vertices that aren't flushed yet.
- Read 32-bit indices the way the PSP does, ignoring the upper 16 bits.
IndexConverter and the fast bounding box test used all 32, so a game
setting them indexed far past the decoded vertices.
- D3D11: Flush in FinishDeferred like the other backends, since indices
are still read from PSP memory at flush time (#10095).
- Don't JIT new vertex decoders once the code space is full.
