The tests for the parsing of the `with` statement were expressed using
eval. This made the tests more complex than necessary and also prevented
the tests from providing value to ECMAScript parsers.

Remove the use of eval and instead express the expectations with literal
source text. Rename the files to make each test's purpose more clear.

These tests are syntactically equivalent to
`test/language/statements/with/12.10.1-7-s.js` and may therefore be
removed without degrading coverage.

While `test/language/statements/with/12.10.1-9-s.js` differs slightly in
the pattern used to enable strict mode, the relevant behavior of the
"use strict" directive prologue is expressly tested via
`test/language/directive-prologue/func-expr-inside-func-decl-parse.js`.
