Extend libcc1's with an API for C++ support.
Extend libcc1's C API to distinguish between integral types with the
same width, as in C++. Likewise for float types.
Export small bits of functionality from the C++ front-end for use in
libcc1. Add support for the C++ front-end to look up names and
addresses using a libcc1-registered binding oracle. Add support for
global friends.

The runtime.dbgvars initializer looks like
var dbgvars = []dbgVar{
{"allocfreetrace", &debug.allocfreetrace},
}
Because the field address was not recognized as valid for a static
initializer, the variable was initialized at runtime. Normally that
would be fine, but for the runtime package it meant that dbgvars was
not initialized when it was read by parsedebugvars. That meant that
the GODEBUG environment variable did nothing.
Fixing that revealed that the static initializer checks had to be more
careful about interface types, just like the existing is_constant
methods.
