[PATCH] Disable x86 tail call optimization under PIC mode

[Reid Kleckner]

You removed the musttail call change, but also removed the supporting code that arranges to jump through ECX, so I don't think this will work either.

I commented on the bug, I'm trying to understand why the GOT reference causes a problem. I don't yet see a codegen bug here.
