Sathya Gunasekaran 8a9e3f64ee [ast] Store correct source position on ThisExpression
Previously, all ThisExpression's had kNoSourcePositions leading to
incorrect error messages like this:

  ➜ d8 -e "function t() { for (const x of this) {} } t();"
  unnamed:1: TypeError: undefined is not a function
  function t() { for (const x of this) {} } t();
            ^
  TypeError: undefined is not a function
      at t (unnamed:1:11)
      at unnamed:1:43


This patch allows creation of a ThisExpression with a source position,
leading to a better error message:

  ➜ d8  -e "function t() { for (const x of this) {} } t();"
  unnamed:1: TypeError: this is not iterable
  function t() { for (const x of this) {} } t();
                                 ^
  TypeError: this is not iterable
      at t (unnamed:1:32)
      at unnamed:1:43


This patch does not remove the existing cached version of
ThisExpression and instead creates a new one when required.

JavaScript tests with expected output

Tests in test/message pass if the output matches the expected output. Message tests are particularly useful when checking for exact error messages.

Tests and their expected output must have the same filename, with the .js and .out extension.

foo.js
foo.out

All tests must end with an exception. The test runner does not handle output from multiple runs, e.g., --stress-opt. Without an exception, the output will be generated several times and the comparison will fail.

You can use a regex in the expected output instead of the exact path:

*%(basename)s:7: SyntaxError: Detected cycle while resolving name 'a'

Empty lines are ignored in the comparison, but whitespaces are not.

Exact details of the test runner are in testcfg.py.
