Remove WINDOWS_SEH code
Fix ICE in debug code over static array enums
Package gcc.unwind and gcc.gthreads
Debug emission cleanups
Fix cross-native compilers

A cross-native compiler is a native compiler (host==target) which was
built on a different architecture (build != (host == target)).

This is not a cross compiler and should be handled just like a normal
native compiler.

More importantly: Paths must be in sync with gcc/d/Make-lang.in
otherwise
the compiler doesn't find the import files.
Fix ICE on Windows/MinGW hosts

The microsoft runtime doesn't support the "%z" format specifier.
Update wiki link in README
Fixup commit for 'Fix cross-native compilers'

$host and $target in libphobos are not the same as the compilers host
and target. Read the pkgvars file to get the correct information.
Set template as local if the instantianting module is being emitted
Assume the prefix length for a symbol fits into an unsigned int
ChangeLog rotate
Change uses of frontend ArrayBase<> to GCC vec<> type.
Don't push CONST_DECLs into the current function
Don't mark TREE_PRIVATE on global symbols. Backend only acknowledges binfo marked as private.
Remove use of ->tdata() in glue.
Don't add __monitor field for extern(C++) classes.
