Version 3.7.4

Proper "libv8.so.3.7.4" SONAME for Linux shared library (issue 1786).

Fix Harmony sets and maps to allow null and undefined as keys (still hidden behind --harmony flag) (issue 1622).

Implement VirtualMemory on FreeBSD to fix build (issue 1807).

Enable VFP instructions for Android.

Fix error handling in Date.prototype.toISOString (issue 1792).

Bug fixes and performance improvements for all platforms.

Not officially supported but noteworthy: Crankshaft for MIPS :-)
