Otherwise, if a Lit script contains escaped substitutions (like %%p in this test https://github.com/llvm/llvm-project/blob/master/compiler-rt/test/asan/TestCases/Darwin/asan-symbolize-partial-report-with-module-map.cpp#L10), they are unescaped during recursive application of substitutions, and the results are unexpected. We solve it using the fact that double percent signs are first replaced with #_MARKER_#, and only after all the other substitutions have been applied, #_MARKER_# is replaced with a single percent sign. The only change is that instead of replacing #_MARKER_# at each recursion step, we replace it once after the last recursion step. Differential Revision: https://reviews.llvm.org/D83894
