Icenowy Zheng c2b7ad3b28 anlogic: support BRAM mapping 
Anlogic FPGAs all have two kinds of BRAMs, one is 9bit*1K when being
true dual port (or 18bit*512 when simple dual port), the other is
16bit*2K.

Supports mapping of these two kinds of BRAMs. 9Kbit BRAM in SDP mode and
32Kbit BRAM with 8bit width are not support yet.

Marcelina Kościelnicka 4e70c30775 FfData: some refactoring. 
- FfData now keeps track of the module and underlying cell, if any (so
  calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
  compilation
- the "flip FF data sense by inserting inverters in front and after"
  functionality that zinit uses is moved onto FfData class and beefed up
  to have dffsr support, to support more use cases

Marcelina Kościelnicka b98376884e test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. 
These parts keep rereading a Verilog module, then using chparam
to test it with various parameter combinations.  Since the default
parameters are on the large side, this spends a lot of time
needlessly elaborating the default parametrization that will then
be discarded.  Fix it with -deref and manual hierarchy call.

Shaves 30s off the test time on my machine.

Marcelina Kościelnicka 8740fdf1d7 ast: Use better parameter serialization for paramod names. 
Calling log_signal is problematic for several reasons:

- with recent changes, empty string is serialized as { }, which violates
  the "no spaces in IdString" rule
- the type (plain / real / signed / string) is dropped, wrongly conflating
  functionally different values and potentially introducing a subtle
  elaboration bug

Instead, use a custom simple serialization scheme.

Marcelina Kościelnicka ea79e16bab xilinx_dffopt: Don't crash on missing IS_*_INVERTED. 
The presence of IS_*_INVERTED on FD* cells follows Vivado, which
apparently has been decided by a dice roll.  Just assume false if the
parameter doesn't exist.

Fixes #2559.
