4d12e94801 Port CallSite methods to C++. 
The goal is to port all of error stack trace formatting to C++.
We will do this bottom up, by first porting helper functions.

Eventually, CallSite methods will only be used when a custom
error stack trace formatter is defined via Error.prepareStackTrace.

4486c47d9b [clang] Use -Wshorten-64-to-32 to enable warnings about 64bit to 32bit truncations. 
Currently only the Win64 bots report this warnings, which adds quite
some overhead to the development process. With this flag we also get
compiler warnings about implicit 64bit to 32bit truncations when
building with clang on Linux/x64 and Mac/x64.
