DIFF: https://github.com/llvm/llvm-project/commit/091adb8807decb4fa1b4e58eba141a06058eb804.diff

LOG: [libc][cmake] move _get_{common|hermetic}_test_compile_options to LLVMLibCTestRules.cmake (#122549)

They're only used in that file, which is more appropriate than
LLVMLibCCompileOptionRules.cmake since they're strictly related to tests.

Remove unused flags param from _get_hermetic_test_compile_options, and flags
that were already set by a prior call to _get_common_test_compile_options.

Added: 
    

Modified: 
    libc/cmake/modules/LLVMLibCCompileOptionRules.cmake
    libc/cmake/modules/LLVMLibCTestRules.cmake

Removed:
