Fix two instances of integer-assignment to string.
...
o In cover.cc, the int-result of mkstemps() was assigned to a string
and silently interpreted as a single-character filename with a funny
value. Fix with the intent: assign the filename.
o in libparse.cc, an int was assigned to a string, but depending on
visible constructors, this is ambiguous. Explicitly cast this to
a char.

attrmap: extend -remove to allow removing attributes with any value.
...
Currently, `-remove foo` would only remove an attribute `foo = ""`,
which doesn't work on an attribute like `src` that may have any
value. Extend `-remove` to handle both cases. `-remove foo=""` has
the old behavior, and `-remove foo` will remove the attribute with
whatever value it may have, which is still compatible with the old
behavior.

bugpoint: new pass.
...
A typical use of `bugpoint` would involve a script with a pass under
test, e.g.:
flowmap -relax -optarea 100
and would be invoked as:
bugpoint -yosys ./yosys -script flowmap.ys -clean -cells
This replaces the current design with the minimal design that still
crashes the `flowmap.ys` script.
`bugpoint` can also be used to perform generic design minimization
using `select`, e.g. the following script:
select i:* %x t:$_MUX_ %i -assert-max 0
would remove all parts of the design except for an unbroken path from
an input to an output port that goes through exactly one $_MUX_ cell.
(The condition is inverted.)

opt_expr: improve simplification of comparisons with large constants.
...
The idea behind this simplification is that a N-bit signal X being
compared with an M-bit constant where M>N and the constant has Nth
or higher bit set, it either always succeeds or always fails.
However, the existing implementation only worked with one-hot signals
for some reason. It also printed incorrect messages.
This commit adjusts the simplification to have as much power as
possible, and fixes other bugs.

memory_collect: do not truncate 'x from \INIT.
...
The semantics of an RTLIL constant that has less bits than its
declared bit width is zero padding. Therefore, if the output of
memory_collect will be used for simulation, truncating 'x from
the end of \INIT will produce incorrect simulation results.

Add "dffinit -noreinit" parameter
...
Sometimes the FF cell might be initialized during the map process, e.g.
some FPGA platforms (Anlogic Eagle and Lattice ECP5 for example) has
only a "SR" pin for a FF for async reset, that resets the FF to the
initial value, which means the async reset value should be set as the
initial value. In this case the DFFINIT pass shouldn't reinitialize it
to a different value, which will lead to error.
Add a "-noreinit" parameter for the safeguard. If a FF is not
technically initialized before DFFINIT pass, the default value should be
set to x.

memory_bram: Fix initdata bit order after shuffling
...
In some cases the memory_bram pass shuffles the order of the bits in a
memory's RD_DATA port. Although the order of the bits in the WR_DATA and
WR_EN ports is changed to match the RD_DATA port, the order of the bits
in the initialization data is not.
This causes reads of initialized memories to return invalid data (until
the initialization data is overwritten).
This commit fixes the bug by shuffling the initdata bits in exactly the
same order as the RD_DATA/WR_DATA/WR_EN bits.

Value of properties can be expression.
...
Example found in the 2007.03 Liberty Reference Manual that was also found
in the wild:
input_voltage(CMOS) {
vil : 0.3 * VDD ;
vih : 0.7 * VDD ;
vimin : -0.5 ;
vimax : VDD + 0.5 ;
}
Current implementation just parses the expression but no interpretation is done.
