Completed implementation for exporting inlined functions using the new binary export format. This change passes (export GO_GCFLAGS=-newexport; make all.bash) but for gc's builtin_test.go which we need to adjust before enabling this code by default. For a high-level description of the export format see the comment at the top of bexport.go. Major changes: 1) The export format for the platform independent export data changed: When we export inlined function bodies, additional objects (other functions, types, etc.) that are referred to by the function bodies will need to be exported. While this doesn't affect the platform-independent portion directly, it adds more objects to the exportlist while we are exporting. Instead of trying to sort the objects into groups, just export objects as they appear in the export list. This is slightly less compact (one extra byte per object), but it is simpler and much more flexible. 2) The export format contains now three sections: 1) The plat- form independent objects, 2) the objects pulled in for export via inlined function bodies, and 3) the inlined function bodies. 3) Completed the exporting and importing code for inlined function bodies. The format is completely compiler-specific and easily changeable w/o affecting other tools. There is still quite a bit of room for denser encoding. This can happen at any time in the future. This change contains also the adjustments for go/internal/gcimporter, necessary because of the export format change 1) mentioned above. For #13241.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
