Log: Enable debug builds with some optimizations turned on.
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.
