516857f3ba [NFCI] Deduplicate builtin FF cell types list 
A few passes included the same list of FF cell types.  Make it a global
const instead.

The zinit pass also seems to include a list like that, but given that
it seems to be completely broken at the time (see #1568 discussion),
I'm going to pretend I didn't see that.

Clean up passes/sat/qbfsat.cc. 
Makes various cosmetic fixes, removes superfluous `hasPort()` check, and uses `emplace_back()` instead of `push_back()`.

01e6850bd3 write_cxxrtl: improve writable memory handling. 
This commit reduces space and time overhead for writable memories
to O(write port count) in both cases; implements handling for write
port priorities; and simplifies runtime representation of memories.

fb0270b752 write_cxxrtl: add support for hierarchical designs. 
Hierarchical design simulations are generally much slower, but this
comes with a major increase in flexibility:
 1. Since the `flatten` pass currently does not support flattening
    of designs with processes, this is the only way to simulate such
    designs with cxxrtl.
 2. Support for hierarchy paves way for simulation black boxes,
    which are necessary for e.g. replacing PHYs with C++ code that
    integrates with the host system.

3376dcf37c write_cxxrtl: avoid undefined behavior on out-of-bounds memory access. 
After this commit, if NDEBUG is not defined, out-of-bounds accesses
cause assertion failures for reads and writes. If NDEBUG is defined,
out-of-bounds reads return zeroes, and out-of-bounds writes are
ignored.

This commit also adds support for memories that start with a non-zero
index (`Memory::start_offset` in RTLIL).

5157691f0e write_cxxrtl: statically schedule comb logic and localize wires. 
This results in further massive gains in performance, modest decrease
in compile time, and, for designs without feedback arcs, makes it
possible to run eval() once per clock edge in certain conditions.

820e3d1dad Remove unnecessary pruning of double-quoting 
In the past I was calling the ILANG_BACKEND::dump_const() to dump
values to an output stream. When these values were strings, the
function used to add quotes around them. The firrtl compiler, in turn,
escaped these quotes and the result was double-quoted strings which
were hard to read.

However I'm now calling design_entity->get_src_attribute() directly
and there is no additional quote being put around it, so we can
safely remove the unnecessary call to str.erase() here.

249876b614 support using previously declared types/localparams/params in package 
(parameters in systemverilog packages can't actually be overridden, so
allowing parameters in addition to localparams doesn't actually add any
new functionality, but it's useful to be able to use the parameter
keyword also)
