pilot directory for replacing flags: [negative] with
negative: errorname

ch07-7.2,7.3: add error names
ch07-rest: insert error names rest of ch07
ch08: add expected error name
ch11: add error name to negative
ch12: put error name in negative

ch13: add error name to negative
only one test, did it manually

ch15: add error name to negative:

ch07: add error name to negative

were not caught by the earlier naive grep for flags: [negative]

correct test descriptions to expect ReferenceError only
enforce parse as block statement by adding `;`
remove needless include of $FAIL.js

expect real errors

ch12: negative error matching

ch13 error regexps

ch14 error regexps
