Enable debug builds with some optimizations turned on.

Browse Source 
A new gyp variable 'v8_full_debug' can be set to 0 in order to turn on optimization level 1 for debug builds. With the default (=1), it builds in debug mode like before.

The intention is to run some bots on the waterfall with this configuration. Tests have a x5 speed-up like that.
