  [JSC][armv7] Fix JSC:polymorphicThunkFor register usage on armv7
https://bugs.webkit.org/show_bug.cgi?id=284305

Reviewed by Yusuke Suzuki.

This code confused the tag register with the value register when
checking for non-cell callees when using JSVALUE32_64.

Correctly check the tag register instead.

* JSTests/stress/link-polymorphic-call-memory-usage.js: Added.
