Class block scoping tests

Class block scoping tests

Class bindings are mutable and lexically scoped, with TDZ semantics.
They may not overlap with var bindings in the same scope. This patch
adds tests for those properties.

File test/mjsunit/harmony/block-scope-class.js (right):

https://codereview.chromium.org/1254003004/diff/1/test/mjsunit/harmony/block-...
test/mjsunit/harmony/block-scope-class.js:7: // Flags: --no-legacy-const
--harmony-sloppy
What does legacy const have to do with it? I see no uses of 'const' in this
test.

test/mjsunit/harmony/block-scope-class.js:13: assertEquals(value,
eval("(function() { 'use strict'; var x = 0; {" + code + "} })()"));
Please wrap to 80 chars here and elsewhere in this file (sad we don't have a
lint for this).
