These settings compile/elab but hangs in sim (no completions). Need to document dependencies/requirements/etc. and test.

`define  LDSTQ_ENTRIES  4        // ?order?
`define  LDSTQ_ENTRIES_ENC  2
`define  STQ_ENTRIES  5
`define  STQ_ENTRIES_ENC  3
`define  STQ_FWD_ENTRIES  2		// number of stq entries that can be forwarded from
`define  LMQ_ENTRIES  4
`define  LMQ_ENTRIES_ENC  2
`define  LGQ_ENTRIES  4
`define  EMQ_ENTRIES  1          // erat miss queue (d-only?)
`define  IUQ_ENTRIES  1 		   // Instruction Fetch Queue Size (lq)
`define  MMQ_ENTRIES  1 		   // MMU Queue Size (lq)

Also, STQ_ENTRIES < 5 fails because of hardcoded values in stq3_cmmt_ptr_q.
