<pre>DFG Is<Blah> versions of TypeOf should fold based on proven input type
https://bugs.webkit.org/show_bug.cgi?id=144409
Reviewed by Geoffrey Garen.
Source/JavaScriptCore:
We were missing some obvious folding opportunities here. I don't know how this affects real
code, but in general, we like to ensure that our constant folding is comprehensive. So this
is more about placating my static analysis OCD than anything else.
I added a bunch of speed/correctness tests for this in LayoutTests/js/regress.

+ DFG Is<Blah> versions of TypeOf should fold based on proven input type
+ https://bugs.webkit.org/show_bug.cgi?id=144409
+
+ Reviewed by Geoffrey Garen.

+ We were missing some obvious folding opportunities here. I don't know how this affects real
+ code, but in general, we like to ensure that our constant folding is comprehensive. So this
+ is more about placating my static analysis OCD than anything else.
+
+ I added a bunch of speed/correctness tests for this in LayoutTests/js/regress.
