Reason for revert:
With fixes for frozen RegExps in https://codereview.chromium.org/2339443002 , it should be web-compatible to put RegExps in strict mode again, per spec.

src/js/regexp.js was one of the few files that was left in sloppy
mode. The ES2017 draft specification requires that writes to
lastIndex throw when the property is non-writable, and test262
tests enforce this behavior. This patch puts that file in strict
mode.

The stand-alone test driver is changed a bit:
- Don't use the errorMessage list. It is used differently in the embedded driver. There it collects parser errors - instead of failure messages.
- Remove html links in description texts. Some test descriptions print a web reference.
The migrated tests fall into 3 categories:
1. Tests outside fast/js
2. Tests that print FAIL messages (and also expect those) - these tests should be examined later if they make sense at all
3. Tests with html links in the test description
