Disable WPO for mini_installer

Disable WPO for mini_installer

We need to do this because when doing a PGO build the /GL flag gets automatically set everywhere, and we're hitting this warning: https://msdn.microsoft.com/en-us/library/b8s7ctwz%28v=vs.90%29.aspx because of the custom memset implementation (https://code.google.com/p/chromium/codesearch#chromium/src/chrome/installer/mini_installer/mini_installer.cc&q=mini_ins&sq=package:chromium&l=862)

PTAL.

[scottmg, 2015-03-26 05:33:35]

(We could probably get rid of that memset (I think both of the reasons in the
code aren't valid any more), but I guess linking to the obj isn't much better
anyway.)

lgtm

Actually, come to think of it, I don't remember ever implementing
IgnoreAllDefaultLibraries in msvs_emulation.py.

So I think mini_installer is probably linking to the CRT. (oops?) So you could
probably just try deleting that implementation instead.

(Actually, not your problem, I'll look into that tomorrow, separately.)
