Update tcl doc, yosys does not return data to tcl 
This pull request is to address YosysHQ/yosys#2980.

The documentation, as originally written, does not make it clear that yosys commands, when used within a tcl script, do not return any value to the tcl script.

This pull request notes this and offers a workaround via tee as noted in the issue.

Henner Zeller 9c41b43191 Use compiler-generated default constructor for RTLIL::Const::Const 
No need for a manual implementation.
While at it: have the constructor that takes a string take a
const string reference instead to avoid a copy.

Mohamed A. Bamakhrama 1822be8792 Observe $TMPDIR variable when creating tmp files 
POSIX defines $TMPDIR as containing the pathname of the directory where
programs can create temporary files. On most systems, this variable points to
"/tmp". However, on some systems it can point to a different location.
Without respecting this variable, yosys fails to run on such systems.
