runtime: noescape some functions/variables
This is in preparation of turning on escape analysis for the
runtime.
- In gccgo, systemstack is implemented with mcall, which is not
go:noescape. Wrap the closure in noescape so the escape analysis
does not think it escapes.
- Mark some C functions go:noescape. They do not leak arguments.
- Use noescape function to make a few local variables' addresses
not escape. The escape analysis cannot figure out because they
are assigned to pointer indirections.
