[Mono-dev] [PATCH] Winx64 struct argument changes

[Bill Holmes]

Hello All,

The attached patch focuses on fixes needed for calls to manged from
native that pass structs by value.

Although there are no PLATFORM_WIN32 checks in this patch, it should
have no runtime impact on any other platform.  This patch only adds
implementation to the ArgValuetypeAddrInIReg cases, which only occur
when running Winx64.

Please let me know if you have any suggestions or if this is good to
commit to trunk and the 2.0 branch.

thanks
