Thanks for fixing all the three bugs. Nemerle compiler boots now on amd64!

There is some other issue with checked/unchecked in the testsuite,
that I'm going to investigate tomorrow.

If somebody's interested in performance numbers, then compiling
Nemerle.Compiler.dll using 64 bit version of mono takes around 16s
while compiling it on the same machine using 32 bit mono -- it takes
13s.

I think that the one of the reasons 64bit version is slower could be
cache cluttering -- there are lots of pointers in objects we use in
the compiler, so some of the objects get twice as big. The top RSS
size in 32 bit mode is 89M, while in 64 bit mode 117M.
