Shrink Heap::m_executables after cleaning it.
<https://webkit.org/b/153682>
Reviewed by Darin Adler.
The Heap::m_executables Vector was never shrunk down, despite sometimes
getting pretty huge (~500kB in my longest-running WebContent process.)
After GC has finished pruning unmarked Executables, shrink the Vector.

(JSC::Heap::clearUnmarkedExecutables):
