Zachary Snow aa35f24290 sv: auto add nosync to certain always_comb local vars 
If a local variable is always assigned before it is used, then adding
nosync prevents latches from being needlessly generated.

Austin Seipp b022fe61a7 opt_dff: fix sequence point copy paste bug 
Newer GCCs emit the following warning for opt_dff:

    passes/opt/opt_dff.cc:560:17: warning: operation on ‘ff.Yosys::FfData::has_clk’ may be undefined [-Wsequence-point]
      560 |      ff.has_clk = ff.has_ce = ff.has_clk = false;
          |      ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Which is correct: the order of whether the read or write of has_clk
occurs first is undefined since there is no sequence point between them.

This is almost certainly just a typo/copy paste error and objectively
wrong, so just fix it.

Lofty d015c2b48a intel_alm: disable 256x40 M10K mode 
This BRAM mode uses both address ports, making it effectively single-port.
Since memory_bram can't presently map to single-port memories, remove it.

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.

Thomas Sailer 4cd2f03e36 preprocessor: do not destroy double slash escaped identifiers 
The preprocessor currently destroys double slash containing escaped
identifiers (for example \a//b ). This is due to next_token trying to
convert single line comments (//) into /* */ comments. This then leads
to an unintuitive error message like this:
ERROR: syntax error, unexpected '*'

This patch fixes the error by recognizing escaped identifiers and
returning them as single token. It also adds a testcase.
