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.
