sweet: Add configurable PGO build env
This CL is simply rebasing mpratt@google.com's cl/498275 to HEAD, and
added the help message.
Use like so:
[[config]]
name = "pgo"
goroot = "/path/to/go/"
[[config.pgoconfig]]
name = "baseline"
envbuild = ["GOFLAGS=-gcflags=all=-d=pgodevirtualize=0"]
[[config.pgoconfig]]
name = "devirtall"
envbuild = ["GOFLAGS=-gcflags=all=-d=pgodevirtualize=1"]
A config using pgoenvbuild attribute will only run profile once for all
sub configs, i.e. pgo baseline and devirtall will be based on the
same profile.
