2667dcd113 cmd/gc: steal escape analysis info when inlining
Usually, there is no esc info when inlining, but there will be when generating inlined wrapper functions.

If we don't use this information, we get invalid addresses on the stack.

Fixes #5056.

20c7e41555 cmd/gc: fix escape analysis bug.
It used to not mark parameters as escaping if only one of the
fields it points to leaks out of the function. This causes
problems when importing from another package.

aa5aaabb0d exp/ssa/interp: (#6 of 5): test interpretation of SSA form of $GOROOT/test/*.go.
The interpreter's os.Exit now triggers a special panic rather
than kill the test process.  (It's semantically dubious, since
it will run deferred routines.)  Interpret now returns its
exit code rather than calling os.Exit.

Also:
- disabled parts of a few $GOROOT/tests via os.Getenv("GOSSAINTERP").
- remove unnecessary 'slots' param to external functions; they
  are never closures.

Most of the tests are disabled until go/types supports shifts.
They can be reenabled if you patch this workaround:

572d984eaa cmd/gc: fix escape analysis
If the analysis reached a node twice, then the analysis was cut off.
However, if the second arrival is at a lower depth (closer to escaping)
then it is important to repeat the traversal.

The repeating must be cut off at some point to avoid the occasional
infinite recursion. This CL cuts it off as soon as possible while still
passing all tests.
