Merge pull request #6064 from YosysHQ/krys/alumacc_widths 
Fix merging comparisons with oversized unsigned subtraction in `alumacc`

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.
