358e52a7f5 Make testing compilation errors more deterministic 
A year ago I submitted a change to replace AnyError with tests for specific
errors (see https://github.com/elves/elvish/commit/87656c99).  This does
something similar for DoesNotCompile. This ensures the test does what
is implied and makes correlating specific unit tests with compilation
errors easier.

This includes a couple of changes to compilation error messages to improve
readability (IMHO) but those are not the primary purpose of this change.

e894ae5f82 Improve the syntax of "try". 
* Require at least one of "except" or "finally" to be present. This fixes #1424.

* Rename "except" to "catch". The former will be deprecated from 0.18.0. This
  addresses #1497.

87656c99fa Replace AnyError in tests with a specific error 
The `AnyError` placeholder error can cause tests to succeed for errors
other than what was expected. That is, the use of `AnyError` can mask
bugs in a unit test. So replace it with the specific error, or error type,
the test expects to be raised.

This does not remove the anyError structure because it is used in
the TestCase.DoesNotCompile() method. To keep the size of this change
as small as possible I want to defer updating that use to a separate
change. However, remove the public AnyError var so future test writers
don't attempt to use it.

d4b4edbbbe Replace legacy lambda with new lambda examples 
I was surprised to see so many legacy lambda syntax examples in the
documentation. This replaces all of them with the new syntax -- excluding
the handful of cases meant to explicitly verify the legacy form is still
valid. This also adds a link to the issue in the release notes which
documents the change in syntax.

This explicitly tests a common error case not currently verified by the
existing unit tests. Thus improving test coverage by one line.  :-)

6a7d99041d pkg/eval: Require the variable used in "set" to already exist. 
This has always been the documented behavior, but up until this point, "set"
actually behaved like the legacy assignment form, which creates the variable if
it doesn't exist yet.

This fixes the discrepancy. Addresses #645.

9a576529a3 Replace ErrArgs with more specific errors 
This also replaces the slightly awkward "arguments here" reason with
"argument count" as the "what" for a typical errs.ArityMismatch
exception. It also reformats most of the constructors so that the "what"
is on the same line. This makes `grep errs.ArityMismatch **.go` more
useful as a result.
