MSVC: Drop default use of /Zm1000 for VS >= 7.1 

From the option documentation of VS >= 7.1:

 "In earlier versions of Visual C++, the compiler used several discrete
  heaps, and each had a finite limit. Currently, the compiler dynamically
  grows the heaps as necessary up to a total heap size limit, and requires
  a fixed-size buffer only to construct precompiled headers. Consequently,
  the /Zm compiler option is rarely necessary."
