lgtm % tests

File test/mjsunit/regress/regress-typedarray-length.js (right):

https://codereview.chromium.org/1034393002/diff/40001/test/mjsunit/regress/re...
test/mjsunit/regress/regress-typedarray-length.js:11: return a.length;
Could you add tests for other properties as well?

Also please add tests for
class C extends Uint8Array {
   get length() { return ...; }
}
