libgo: break dependence on libgcc unwind-pe.h
The C portion of the Go runtime includes the header "unwind-pe.h" from
libgcc, which contains some constants and a few small routines for
decoding pointer values within unwind info. This patch gets rid of
that include and instead adds a re-implementation of that
functionality in the single file that uses it. The intent is to allow
the C runtime portion of libgo to be built without a companion GCC
installation.
