exit opcode doesn't set process return value

[pmichaud]

The 'exit' opcode appears to not set the process return value:

$ cat x.pir
.sub main
    exit 1
.end

$ ./parrot x.pir
$ echo $?
0

This is causing problems for many build scripts in Rakudo -- errors encountered during compilation aren't halting the build (and thus the errors are easily overlooked).

This is resolved (tested in r40200). If someone can verify that a test exists (or write one), we can close this out.

Attached patches to support testing of the exit code of a pir program when tested with Parrot::Test and test to verify the exit operation in a pir program.

A modified version of eirik++'s patch was applied in r40658 which can test exit codes of PIR, PASM and PBC.

I've noticed that by default, PASM and PBC seem to exit with 1. I will create a new ticket for that.
