Eli Bendersky d7170ea5a8 Rewrite test/Linker tests to use FileCheck instead of grep.
Some translations here are not 1x1 because there are grep|grep
chains that are non-trivial to implement in terms of FileCheck features. I
made an effort for the tests to remain as similar as possible; do let me know
if you notice anything fishy. The good news are that some buggy tests were
fixed (grep | not grep - a bug waiting to happen).

; The funcresolve pass will (intentionally) llvm-link an _internal_ function
; body with an external declaration. Because of this, if we LINK an internal
; function body into a program that already has an external declaration for
; the function name, we must rename the internal function to something that
; does not conflict.
