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.

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.

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).

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.

write_cxxrtl: elide wires for results of comb cells used once.
...
This results in massive gains in performance, equally massive
reduction in compile time, and improved readability.

write_cxxrtl: new backend.
...
This commit adds a basic implementation that isn't very performant
but implements most of the planned features.

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.

allowing parameters in addition to localparams doesn't actually add any
