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.

bugpoint: avoid infinite loop between -connections and -wires

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.

Marcelina Kościelnicka 0aad88a2fb Add clean_zerowidth pass, use it for Verilog output. 
This should remove instances of zero-width sigspecs in the netlist,
avoiding problems in the Verilog backend with emitting them.

See #3103.

Marcelina Kościelnicka d019b4e681 rtlil: Dump empty connections when whole module is selected. 
Without this, empty connections will be always skipped by `dump`, since
they contain no selected wires.  This makes debugging rather confusing.

Catherine 55c9fb3b18 cxxrtl: preserve interior memory pointers across reset. 
Before this commit, values, wires, and memories with an initializer
were value-initialized in emitted C++ code. After this commit, all
values, wires, and memories are default-initialized, and the default
constructor of generated modules calls the reset() method, which
assigns the members that have an initializer.

write_verilog: dump zero width sigspecs correctly

whitequark 86f2804dc3 write_verilog: dump zero width sigspecs correctly. 
Before this commit, zero width sigspecs were dumped as "" (empty
string). Unfortunately, 1364-2005 5.2.3.3 indicates that an empty
string is equivalent to "\0", and is 8 bits wide, so that's wrong.

After this commit, a replication operation with a count of zero is
used instead, which is explicitly permitted per 1364-2005 5.1.14,
and is defined to have size zero. (Its operand has to have a non-zero
size for it to be legal, though.)

PR #1203 has addressed this issue before, but in an incomplete way.
