5dda3a14ff Fixup some of the re-mapping logic. 
- Add IDEMPOTENT_CHECK define to perform some expected idempotent
   operations more than once to verify they work as expected.

5e96740451 [FPGA interchange] Small fix to get_net_type. 
If get_net_type was called before the driver was placed, it could return
the wrong value.

8d1eb0a195 Initial lookahead for FPGA interchange. 
Currently the lookahead is disabled by default because of the time to
compute and RAM usage.  However it does appear to work reasonably well
in testing.  Further effort is required to lower RAM usage after initial
computation, and explore trade-off for cheaper time to compute.

significantly slower with the use of caching.

06bcde6243 Correct some bugs in writing of physical netlist w.r.t. site sources. 
Local site sources should have their driving BEL pin included in the net
so that the site wire is driven by an output BEL pin.

e7d81913a4 Add "checkPipAvailForNet" to Arch API. 
This is important for distiguishing valid pseudo pips in the FPGA
interchange arch. This also avoids a double or triple lookup of
pip->net map.
