Iztok Jeras 6b44f4321e dfflibmap: picking first instead of last cell with smallest area 
In a standard cell library cells are usually ordered from weakest to strongest.
Sometimes the two weakest cells have the same area.
Previously the stroner (last) of the two was selected,
now the weaker (first is selected).

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.
