Support for building Chrome using Clang.
To build, set the clang=1 gyp_define.
This patch is the culmination of many months of effort and many
patches. It contains the minimal changes to Chrome that
are Clang-specific.
With this, I can build the "chrome" target. Once this patch
is in, we can incrementally fix bits of Chrome and various
tests and remove the Clang-specific workarounds.
