Ben Widawsky a98069d762 verilog_parser: Fix Bison warning
As of Bison 2.6, name-prefix is deprecated. This fixes
frontends/verilog/verilog_parser.y:99.1-34: warning: deprecated directive, use ‘%define api.prefix {frontend_verilog_yy}’ [-Wdeprecated]
 %name-prefix "frontend_verilog_yy"

For details: https://www.gnu.org/software/bison/manual/html_node/Multiple-Parsers.html

Udi Finkelstein ac10e7d96d Initial implementation of elaboration system tasks
(IEEE1800-2017 section 20.11)

This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.
