Reland of http://crrev.com/241548.

It broke on the main waterfall after going through the CQ. Two changes:
* No-op the loading test on 64-bit.
* Remove the 'IgnoreAllDefaultLibraries' directive. This seems to exclude
the CRT on some builders.

Original CL description:
 Chrome browser process DLL blacklist.

 This patch allows for blocking of module loading in the browser process.
 It does not actually prevent any modules from loading.
