RetContinuation PMC

[bacek]

Hello.

Solely purpose of RetContinuation was to quickly recycle Continuation after .invoke. After merging fix for #1393 it's not true any more. Now RetContinuation can be replaced with just Continuation PMC.

Attached a patch which converts internal usage of RetCon into straight Continuation.

All tests pass except t/op/calling.t #47:

.sub main :main
    $P0 = eval("print \"Foo!\\n\"")
    $P0()
    end
.end

.sub eval
    .param string code
    code = ".sub main :main :anon\n" . code
    code = code . "\n.end\n"
    $P0 = compreg "PIR"
    .tailcall $P0(code)
.end

Fails with:

invoke() not implemented in class 'String' current instr.: 'main' pc 15 (/Users/coke/sandbox/parrot/t/op/calling_47.pir:3)

Remove usage of RetCon in the src/

Updated the attachment.

Unfortunately, it now fails all t/pmc/pack*.t tests. - I am assuming this is because PBC_COMPAT was bumped (because a core PMC was removed.).

I've tried regenerating the native pbcs used by the packfile tests, but tools/dev/mk_native_pbc fails for me on linux & OS X intel.

the extend test also needs some attention once this issue is resolved.

Recent branch commits have already bumped PBC_COMPAT, so there will be a conflict there.

Patch (with minor tweaks) applied in r45867. Native PBCs rebuild. Closing ticket.
