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. Reviewed-on: https://go-review.googlesource.com/90235 From-SVN: r259861
