[patch] coreclr/com check + icall cleanup

Rate this Message:
Hello,
Two small/easy patches for review. The first one avoid calling mono_com_init when coreclr is enabled*. This avoid a crash if some assembly use [ComImport] on a type and throw a TypeLoadException - which is what happens in Silverlight. * For some reason (I guess it use COM for it's platform code, while Moonlight does not) Silverlight expose [ComImport] but otherwise does not support COM (as least for application code). Second patch removes some internal calls (all strings except one) that are not used (anymore) in the class libraries. Sebastien p.s. both patches were created from 2-6 branch but I'll commit them against HEAD too.

The icall removal patch is ok.
The second one is tricky. Do we really want to completely disable COM support when running under the sandbox? It does make sense for moonlight, but not for other users of coreclr. I believe we should only fail COM for non-platform assemblies which has the same result for moonlight but won't bite future users of the sandbox code.

Well it won't change anything for Moonlight[1] but it will still bite any other (well future) user of coreclr unless the BCL they provide offers the required COM types [2]. Otherwise it will simply abort (like id does today). Sebastien [1] unless someone adds a [ComImport] somewhere in the platform code - but that would not pass our test suite :) [2] A added a FIXME in the patch about this.
