Add support for Math.imul
​https://bugs.webkit.org/show_bug.cgi?id=115143

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

Add support for Math.imul, a thunk generator for Math.imul,
and an intrinsic.

Fairly self explanatory set of changes, DFG intrinsics simply
leverages the existing ValueToInt32 nodes.
