<rdar://problem/6309878> Need more granular control over allocation of executable memory (21783)
<​https://bugs.webkit.org/show_bug.cgi?id=21783>

Reviewed by Cameron Zwarich and Sam Weinig

Add a new allocator for use by the JIT that provides executable pages, so
we can get rid of the current hack that makes the entire heap executable.

1-2% progression on SunSpider-v8, 1% on SunSpider. Reduces memory usage as well!
