tests/alumacc: Add broad merge test 
Mixes input cells, signedness, input width, output width.
Within the things that are `random.choice`, they *should* always be equivalent, but add a seed arg anyway just in case one day they're not.

alumacc: cmp_mergeable function 
Replace all the existing mergeable checks with a call to a single function.
Fix remaining discrepencies (undersized output and mismatched signed inputs).

alumacc: Fix get_lt for oversized output 
Current behavior uses the output width to determine the MSb(s), however this is not correct if the output is larger than the inputs (which doesn't happen when creating an `$alu` for a compare op, but does when folding a compare op into an arithmetic `$alu`).

tests/opt: Add extra alumacc test 
Checks equivalence when folding an `$lt` (or equivalently a `$gt`) into a `$sub`.
Currently failing, fix incoming.

xilinx_srl: keep the clock enable on FDRE shift registers 
run_fixed inferred a fixed length shift register from a chain of FDRE
flops but assigned it ENPOL 2, which the cells_map template reads as no
enable and ties the enable high. FDRE has an active high clock enable, so
the shift register shifted every cycle and ignored stalls. Give FDRE and
FDRE_1 chains ENPOL 1 so the active high enable is kept.

Add tests/arch/xilinx/xilinx_srl_enable.ys covering the FDRE path.

mul2dsp: normalize operand order 
Move the operand commute that puts the wider operand on A ahead of the
min-width checks. Checking the min-widths first made an asymmetric rule
(DSP_A_MINWIDTH != DSP_B_MINWIDTH) match only products that already had the
wider operand on A; a product in the other order was rejected before the
normalization.

symfpu: Add -compare mode 
Also `min` and `max` ops.  RISC-V uses IEEE 754-2019 semantics where `min(+0,-0) == -0` and `max(+0,-0) == +0` so we do the same here.  We could make it optional, but as I understand it the newer behavior is still backwards compatible (since previously it was valid to have selected either).

tests/symfpu: Extra muladd tests 
Switch inputs back to `anyseq`, and add coverage for muladd with constant multiplier output and varying addend (also an assertion).
Use an `ifdef` to control clocked properties (because of the assertion, it's no longer just covers that are clocked).

tests/symfpu: Testing sqrt 
Coverage supports `sqrt`, including new general rounding detection instead of just inf/ebmin/zero (since they aren't possible with `sqrt`).
