Indirect function and method calls should leak everything,
but they didn't.
This fix had no particular effect on the cost of running the
compiler on html/template/*.go and added a single new "escape"
to the standard library:
syscall/syscall_unix.go:85: &b[0] escapes to heap
in
if errno := m.munmap(uintptr(unsafe.Pointer(&b[0])),
uintptr(len(b))); errno != nil {
Added specific escape testing to escape_calls.go
(and verified that it fails without this patch)
I also did a little code cleanup around the changes in esc.c.
Fixes #10925
