cmd/internal/gc: convert Val.U to interface{}
This CL was generated by updating Val in go.go
and then running:
sed -i "" 's/\.U\.[SBXFC]val = /.U = /' *.go
sed -i "" 's/\.U\.Sval/.U.\(string\)/g' *.go *.y
sed -i "" 's/\.U\.Bval/.U.\(bool\)/g' *.go *.y
sed -i "" 's/\.U\.Xval/.U.\(\*Mpint\)/g' *.go *.y
sed -i "" 's/\.U\.Fval/.U.\(\*Mpflt\)/g' *.go *.y
sed -i "" 's/\.U\.Cval/.U.\(\*Mpcplx\)/g' *.go *.y
No functional changes. Passes toolstash -cmp.
This reduces the size of gc.Node from 424 to 392 bytes.
This in turn reduces the permanent (pprof -inuse_space)
memory usage while compiling the test/rotate?.go tests:
test old(MB) new(MB) change
rotate0 379.49 364.78 -3.87%
rotate1 373.42 359.07 -3.84%
rotate2 381.17 366.24 -3.91%
rotate3 374.30 359.95 -3.83%
CL 8445 was similar to this; gri asked that Val's implementation
be hidden first. CLs 8912, 9263, and 9267 have at least
isolated the changes to the cmd/internal/gc package.
Updates #9933.

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
