[clang-repl] Remove redundant tests

[Hahnfeld]

Summary

They only need to be tested once in execute.cpp and fail.cpp.

Thanks!

clang/test/Interpreter/fail.cpp

 // FIXME: There're some inconsistencies between interactive and non-interactive
 // modes. For example, when clang-repl runs in the interactive mode, issues an
 // error, and then successfully recovers if we decide it's a success then for
 // the non-interactive mode the exit code should be a failure.
 // RUN: clang-repl "int x = 10;" "int y=7; err;" "int y = 10;"
-// RUN: clang-repl "int i = 10;" 'extern "C" int printf(const char*,...);' \
-// RUN:            'auto r1 = printf("i = %d\n", i);' | FileCheck --check-prefix=CHECK-DRIVER %s
 // REQUIRES: host-supports-jit
 // UNSUPPORTED: system-aix
-// CHECK-DRIVER: i = 10
 // RUN: cat %s | not clang-repl | FileCheck %s
