Ross McIlroy 05207b098a [Interpreter] Replace --ignition flag with a --stress-fullcodegen
Removes the --ignition flag which is now on by default. Adds a
--stress-fullcodegen flag which enables running all functions supported
by fullcodegen to be compiled by fullcodegen.

This will enable moving parser internalization later when we are not
stressing fullcodegen or compiling asm.js functions.
