Until now, String.prototype.{trimLeft,trimRight} were non-standard
language extensions, required for Web compatibility.
The proposal at https://github.com/tc39/proposal-string-left-right-trim
standardizes this functionality as String.prototype.{trimStart,trimEnd},
and defines String.prototype.{trimLeft,trimRight} as aliases for
backwards compatibility.
This patch implements that proposal behind the --harmony-string-trimming
flag.

The timezone offset in effect on Dec 25, 1995 won't be applicable
in years far away from 1995 (e.g. year 1111).
Calculate the timezone offset in Feb 1, 1995 and run other tests
on the same day.
This issue has been hidden because the current implementation doesn't
take into account the history of timezone offset changes(crbug.com/3547),
but was exposed when a correct implementation based on ICU was tried.

I added additional exception logging in the execution.py since
errors in processing results were really difficult to debug.
There is a problem on Windows with class serialization when
it comes from dynamically loaded module. To fix it I moved all
output processors to the tools/testrunner/outproc/ and import
them in test/*/testcfg.py.

The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:
Array.prototype.sort.call(null, 1);
Behavior before applying the patch (incorrect message):
TypeError: Array.prototype.sort called on null or undefined
Expected behavior:
TypeError: The comparison function must be either a function or
undefined
This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.
The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

Tracking labels for most of these statements made no difference: only
try-statements require the special treatment of being wrapped in a
block. The previous code existed to support strong mode, which is
long gone.
This also results in a tiny regression of the error message for
a labelled `continue` statement targeting itself, but I'm not
convinced that anyone would ever intend to label a continue
statement (and Chakra and SpiderMonkey give similarly inaccurate
error messages for this case).
This is effectively a revert of d8bccfe974.
