Clarify bugpoint documentation regarding output 
Bugpoint's current documentation does specify that the result of a run is stored as the current design,
however it's easy to skim over what that means in practice. 

Add a documentation comment to explain specifically that an after bugpoint `write_xyz` pass is required to save
the reduced design.

whitequark 00e7dec7f5 Replace "ILANG" with "RTLIL" everywhere. 
The only difference between "RTLIL" and "ILANG" is that the latter is
the text representation of the former, as opposed to the in-memory
graph representation. This distinction serves no purpose but confuses
people: it is not obvious that the ILANG backend writes RTLIL graphs.

Passes `write_ilang` and `read_ilang` are provided as aliases to
`write_rtlil` and `read_rtlil` for compatibility.

whitequark a342d6db49 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.)
