[llvm-lit] Expected string not found in input error in compiler-rt when testing with lit internal shell

[Harini0924]

When testing with the lit internal shell, a compiler-rt test fails with "Expected string not found in input" errors.
For example, ignore_lib0.cpp:

FAIL: ThreadSanitizer-x86_64 :: ignore_lib0.cpp (89 of 9570)
******************** TEST 'ThreadSanitizer-x86_64 :: ignore_lib0.cpp' FAILED ********************
Exit Code: 1

files with failure:

• compiler-rt/test/tsan/ignore_lib0.cpp

Steps to reproduce:

1. CMAKE config:

cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;llvm;clang-tools-extra;lld;lldb;bolt;mlir;libclc;polly" -DLLVM_ENABLE_RUNTIMES="compiler-rt;libc;libcxx;libunwind;libcxxabi" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -B build -S .

2. Using the following commands to test each subproject using the lit internal shell
   LIT_USE_INTERNAL_SHELL=1 ninja check-clang
LIT_USE_INTERNAL_SHELL=1 ninja check-compiler-rt
