do not write failed template instantiations or parts of these to the object file

no codegen for parts of failed template instantiations
Increase temp space in mtype.c/Type::getTypeInfoIdent(int)

Compiling druntime+phobos, this method is called 1245 times. 1104 times malloc()
is called - that's 89%! Increasing the size from 40 to 128, malloc() is only
called 128 times, which looks better. (Average length is 66.)
This may still too small - compiling some unit tests I have seen mangled names
with length up to 16745.

Alternatives are:
- use always malloc()
- use always alloca()

The same seems to be true variable out of type OutBuffer. But I do not have
collected the numbers here.
silence warning about missing return
add assert to isError
New sc.ini with expanded 64-bit support

Note: Requires phobos64.lib to be in lib64 rather than lib

Fixes issue #11266

Should work for all versions of Visual Studio 2008+ when dmd is used
within the Visual Studio Command Prompt.

Works in conjunction with the Windows dmd installer to automatically set
appropriate paths so 64-bit dmd compilation can be used outside of the
Visual Studio Command Prompt
