fourthTier: The Math object should not be polymorphic
​https://bugs.webkit.org/show_bug.cgi?id=117576

Reviewed by Oliver Hunt.

Fill in the Math object eagerly, to avoid its structure changing during
execution. There are lots of ways to skin this cat; this one seemed
easiest, and justified given the relative hotness of math operations.

20% speedup on DSP-filtrr tests, small speedups on a few Kraken tests.
