LGTM modulo test

https://codereview.chromium.org/1853763002/diff/20001/test/cctest/test-parsin...
File test/cctest/test-parsing.cc (right):

https://codereview.chromium.org/1853763002/diff/20001/test/cctest/test-parsin...
test/cctest/test-parsing.cc:7885: "class C { constructor (x: number);
constructor (x) {} }",
Also try in the opposite order.

test/cctest/test-parsing.cc:7886: "class C { f (x: number) : number; f (x) {
return x; } }",
Same here.

It is not 100% clear if that should be valid or not.  As I understand it, the
idea in TS is that you can have zero or more function/method/constructor
signatures before the (single) implementation of the
function/method/constructor.

A test with those reversed would pass here because, after parsing, these
signatures are equivalent to empty statements.  But I think it would be
misleading to include such tests, which fail in TS (with a semantic error).
