Henner Zeller e2f044ec4a Place <file>:<line>:<col> first in an error message 
This is the same as most compilers (e.g. gcc and clang) but also
verilog tools (e.g. yosys) output error mesasge in a standardized form.

This form can immediately be parsed by IDE tools that can jumping
through a list of error messages, placing the cursor at the given
file position.

This change simply re-arranges the error message printing to conform to that
standard.
