There are two ways nohup(1) might be implemented:
it might mask away the signal, or it might set the handler
to SIG_IGN, both of which are inherited across fork+exec.
So two fixes:
* Make sure to preserve the inherited signal mask at
minit instead of clearing it.
* If the SIGHUP handler is SIG_IGN, leave it that way.
Fixes#4491.

Unexported field and method names that appear in the
export data (as part of some exported type) are fully
qualified with a package id (path). In some cases, a
package with that id was never exported for any other
use (i.e. only the path is of interest).
We must not create a "real" package in those cases
because we don't have a package name. Entering an
unnamed package into the map of imported packages
makes that package accessible for other imports.
Such a subsequent import may find the unnamed
package in the map, and reuse it. That reused and
imported package is then entered into the importing
file scope, still w/o a name. References to that
package cannot resolved after that. Was bug.

The lowering of ast.RangeStmt now has three distinct cases:

The Range instruction and the interpreter's "iter"

2) rangeChan for channels; approximately:
for {

3) rangeIndexed for slices, arrays, and *array; approximately:
for k, l = 0, len(x); k < l; k++ {
v = x[k]
