The stack barrier code will need a bookkeeping structure to keep track of the overwritten return PCs. This commit introduces and allocates this structure, but does not yet use the structure. We don't want to allocate space for this structure during garbage collection, so this commit allocates it along with the allocation of the corresponding stack. However, we can't do a regular allocation in newstack because mallocgc may itself grow the stack (which would lead to a recursive allocation). Hence, this commit makes the bookkeeping structure part of the stack allocation itself by stealing the necessary space from the top of the stack allocation. Since the size of this bookkeeping structure is logarithmic in the size of the stack, this has minimal impact on stack behavior.

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.
